How to Cite Two Authors in APA Style: A Step-by-Step Guide
Citing sources is an essential aspect of academic writing, and the American Psychological Association (APA) style is one of the most widely used citation formats. When citing two authors in APA style, it's crucial to follow the correct format to ensure accuracy and credibility. In this article, we'll walk you through the process of citing two authors in APA style, highlighting the key differences between citing two authors in the same parentheses and citing two authors in the in-text citation.
Citing Two Authors in the Same Parentheses
When citing two authors who contributed to the same source, you should list their names separated by an ampersand (&) in the parentheses, followed by the publication year. For example:
| Example | Explanation |
|---|---|
| (Author1, Author2, 2020) | Lists the names of two authors separated by an ampersand (&) in the parentheses, followed by the publication year. |

For instance, if you're citing a study by Johnson and Smith (2020), the in-text citation would appear as (Johnson & Smith, 2020). If you're citing a source with three authors, you would list all three names separated by commas, as shown below:
| Example | Explanation |
|---|---|
| (Author1, Author2, Author3, 2020) | Lists the names of three authors separated by commas in the parentheses, followed by the publication year. |
Citing Two Authors in the In-Text Citation
When citing two authors in the in-text citation, you should list their names separated by an ampersand (&) followed by the publication year, just like in the parentheses. However, if you're citing multiple sources by different authors, you should list the sources in alphabetical order, separated by semicolons, and include the publication year. For example:
| Example | Explanation |
|---|---|
| Johnson & Smith (2020) found that...; Johnson & Thompson (2019) also discovered that... | Lists multiple sources by different authors in alphabetical order, separated by semicolons, and includes the publication year. |
Citing Authors with the Same Last Name
When citing authors with the same last name, you should include their first initial in the parentheses to avoid confusion. For example:
| Example | Explanation |
|---|---|
| (J. Johnson & S. Johnson, 2020) | Includes the first initial of the authors with the same last name in the parentheses to avoid confusion. |
Citing Authors with No Last Name or Incomplete Last Name
When citing authors with no last name or an incomplete last name, you should use their initials in the parentheses. For example:
| Example | Explanation |
|---|---|
| (M. Johnson & S. J., 2020) | Includes the initials of the authors with no last name or an incomplete last name in the parentheses. |
Additional Tips and Examples
Here are some additional tips and examples to help you master the art of citing two authors in APA style:
- When citing multiple sources by the same author, list the sources in chronological order by publication year.
- When citing multiple sources by different authors with the same last name, include the first initial of each author in the parentheses.
- When citing authors with no last name or an incomplete last name, use their initials in the parentheses.
- Always proofread your citations to ensure accuracy and consistency.
