How to Cite a Conference Paper in APA, MLA, Chicago, and IEEE
Cite conference papers, proceedings, presentations, and poster sessions correctly in APA, MLA, Chicago, and IEEE.
Conference papers are a major source of cutting-edge research, especially in fields like computer science, engineering, and the sciences. But citing them can be tricky because "conference paper" covers several distinct formats -- published proceedings, unpublished presentations, poster sessions, and virtual talks. Each has different citation rules depending on your style guide.
Published Proceedings vs. Unpublished Presentations
Before you start formatting, identify what kind of conference source you have. This distinction matters because it changes the citation format entirely.
Published proceedings are conference papers that have been collected and published, usually as a book, book chapter, or journal supplement. They're peer-reviewed and permanently available. You cite them like book chapters or journal articles, depending on the publication format.
Unpublished presentations are talks, slides, or papers delivered at a conference but never formally published. They're harder to cite because your reader may not be able to retrieve them.
If the paper has a DOI, it's almost certainly published proceedings. If you found it through a conference website or received it from the presenter, it's likely unpublished. For more on how DOIs help identify published sources, see our guide on what a DOI is and how to use it in citations.
APA 7th Edition
Published Conference Proceedings (Book Chapter)
When a conference paper appears in an edited proceedings volume, treat it like a book chapter:
Author, A. A., & Author, B. B. (Year). Title of paper. In C. C. Editor (Ed.), Title of proceedings (pp. xx--xx). Publisher. https://doi.org/xxxxx
Example:
Nakamura, T., & Perez, L. (2025). Efficient transformer architectures for low-resource languages. In R. Chen (Ed.), Proceedings of the 2025 Conference on Empirical Methods in Natural Language Processing (pp. 142--158). Association for Computational Linguistics. https://doi.org/10.18653/v1/2025.emnlp-main.12
Published Conference Proceedings (Journal Format)
Some conferences publish their proceedings as a special issue or supplement of a journal. In that case, cite it like a journal article:
Author, A. A. (Year). Title of paper. Journal Name, Volume(Issue), pages. https://doi.org/xxxxx
Conference Presentation (Unpublished)
For talks or papers presented at a conference but not formally published:
Author, A. A., & Author, B. B. (Year, Month Day--Day). Title of presentation Conference presentation. Name of Conference, Location. https://url-if-available
Example:
Garcia, M. S. (2025, October 8--10). Climate modeling with physics-informed neural networks Conference presentation. Annual Meeting of the American Geophysical Union, San Francisco, CA, United States.
Poster Session
Author, A. A. (Year, Month Day--Day). Title of poster Poster presentation. Name of Conference, Location.
Example:
Kim, J., & Okafor, N. (2025, June 14--16). Microplastic concentrations in freshwater invertebrates Poster presentation. Society for Freshwater Science Annual Meeting, Milwaukee, WI, United States.
Online or Virtual Conference
For virtual conferences, replace the physical location with "Virtual" or "Online":
Author, A. A. (2025, March 3--5). Title of presentation Conference presentation. Name of Conference, Online. https://url-if-available
MLA 9th Edition
MLA uses its core elements template for conference papers, which means you identify the containers (the proceedings, the conference, the publisher) and work outward.
Published Conference Proceedings
Author Last, First. "Title of Paper." Title of Proceedings, edited by Editor First Last, Publisher, Year, pp. xx--xx. Database or Website, doi or URL.
Example:
Nakamura, Takeshi, and Lucia Perez. "Efficient Transformer Architectures for Low-Resource Languages." Proceedings of the 2025 Conference on Empirical Methods in Natural Language Processing, edited by Rui Chen, Association for Computational Linguistics, 2025, pp. 142--58.
Conference Presentation (Unpublished)
Author Last, First. "Title of Presentation." Name of Conference, Day Month Year, Location. Conference presentation.
Example:
Garcia, Maria S. "Climate Modeling with Physics-Informed Neural Networks." Annual Meeting of the American Geophysical Union, 8 Oct. 2025, San Francisco. Conference presentation.
Poster Session
Kim, Jiyeon, and Nkem Okafor. "Microplastic Concentrations in Freshwater Invertebrates." Society for Freshwater Science Annual Meeting, 14 June 2025, Milwaukee. Poster presentation.
Chicago 17th Edition
Chicago offers two systems. Most humanities courses use Notes-Bibliography; most science and social science courses use Author-Date.

IEEE
IEEE is the dominant style in engineering and computer science, and conference papers are especially common in IEEE publications.
Published Conference Proceedings
1 A. A. Author and B. B. Author, "Title of paper," in Proc. Name of Conf., City, Country, Year, pp. xx--xx, doi: xxxxx.
Example:
1 T. Nakamura and L. Perez, "Efficient transformer architectures for low-resource languages," in Proc. 2025 Conf. Empirical Methods Natural Language Processing, Singapore, 2025, pp. 142--158, doi: 10.18653/v1/2025.emnlp-main.12.
Conference Presentation (No Published Paper)
1 A. A. Author, "Title of presentation," presented at the Name of Conf., City, Country, Month Day, Year.
Example:
1 M. S. Garcia, "Climate modeling with physics-informed neural networks," presented at the Annual Meeting Amer. Geophysical Union, San Francisco, CA, USA, Oct. 8--10, 2025.
IEEE abbreviates conference names, journal titles, and location details. Check the IEEE Reference Guide for standard abbreviations. For a full walkthrough of IEEE formatting, see our IEEE citation style guide.
Common Mistakes
Treating all conference papers like journal articles. Published proceedings that appear in a book format should be cited as book chapters, not journal articles. Check the publication format before choosing your template.
Omitting the DOI. If the conference paper has a DOI, include it. It's the most reliable way for readers to locate the source. Many conferences now assign DOIs to individual papers within their proceedings.
Confusing the conference name with the proceedings title. The conference is the event (e.g., "Annual Meeting of the ACM"). The proceedings is the published collection (e.g., Proceedings of the 2025 Annual Meeting of the ACM). Some citation styles need both; others only need one.
Forgetting to note the presentation type. APA specifically requires bracketed descriptions like Conference presentation or Poster presentation. Leaving this out makes it unclear what kind of source you're citing.
Using the wrong date. For published proceedings, use the publication year. For unpublished presentations, use the date(s) of the conference. These aren't always the same.
Quick Reference Table
| Element | APA | MLA | Chicago | IEEE |
|---|---|---|---|---|
| Author format | Last, Initials. | Last, First. | First Last (notes) | Initials. Last |
| Paper title | Sentence case | Title case in quotes | Title case in quotes | Sentence case in quotes |
| Proceedings title | Italic, sentence case | Italic, title case | Italic, title case | Italic, abbreviated |
| DOI/URL | Required if available | Required if available | Required if available | Required if available |
| Presentation type | Bracketed | Described at end | In parenthetical note | "presented at" |
Try It with CiteTools
Conference papers have more variations than almost any other source type, and getting the format right depends on whether the paper was published, how it was published, and which style you're using. Instead of sorting through all those variables yourself, paste your conference paper's DOI into CiteTools.io and get a correctly formatted citation in seconds. We handle published proceedings, presentations, and poster sessions across all six styles.
