Vaughn Miller was a student at Greendale Community College. He is an avid hacky sack player and musician and is often seen around campus engaging in both activities. Something of a hippie stereotype, he's often barefoot and shirtless with a chill and laid back disposition. A quirk of his is that he has a tendency to greet and say goodbye to people three different ways. He used to date Britta, but it ended badly which led to him writing a break up song about her. He later became interested in Annie, eventually dating her despite initial objections from Jeff and Britta. His first appearance was in the Season One episode "Social Psychology". He is portrayed by Eric Christian Olsen.
Vaughn is first introduced in "Social Psychology" playing hacky sack in the courtyard. Britta introduces him to Jeff as a friend, but would later reveal she is in a relationship with him. After he wrote a love poem to Britta, she became apprehensive about how fast the relationship was developing. She shows the poem to Jeff to get his opinion, unaware that he was feeling jealous of Vaughn dating her. He subsequently showed it to Shirley and then later to the rest of the study group. When Vaughn walks in and sees them mocking it, he immediately ends things with Britta seeing it as a violation of trust.
He returned in Home Economics still bitter towards Britta. After Pierce joins his band, he premieres the song "Gettin' Rid of Britta". After an argument with Pierce over writing credits, however, he shifts his anger at the older study group member and rewrites the song with another student named MC Dan Harmon into "Pierce You Are A B". He then discovers Pierce collaborating with M.C. On a rap response to his song furthering the animosity between him and Hawthorne.
In Romantic Expressionism, Annie reveals to Britta that she likes Vaughn and asks for her blessing. Britta gives it to her and later informs Jeff. Jeff tells Britta that Vaughn is a "gateway douchebag," and Annie shouldn't be dating him because she's still pretty young. The two hatch a scheme to break them up by getting Troy to like Annie. Jeff describes to him "a complete stranger who happened to be in their study group," and Troy sees Annie in a whole new light. He later flirts with her in the cafeteria, and when Vaughn sees what's going on, Annie reveals that she previously did like Troy but is over him now. Because a similar thing happened when he asked about Britta's feelings towards Jeff, Vaughn declares that their study group is evil and storms off. Annie asks Troy why he would do something like that, and he tells her about his conversation with Jeff and Britta earlier. Annie rushes to the library and tells Britta and Jeff how super cool and mature they are for getting involved in her love life, adding that since they're idiots, she should let them know she's being sarcastic, making them feel bad. Britta reveals that she didn't want Annie to date Vaughn because he was mean to her, and that Jeff is probably jealous that Vaughn was kissing his debate/make-out partner. Vaughn later meets Annie and the study group just outside of the study room building. When asked if he received Annie's voice messages, he says that he threw his phone into the river. Vaughn explains that if he couldn't call Annie and be with her, he didn't see a reason to have a phone. He then sings her "Annie's Song," a song that he wrote about her. Britta tells Annie that she doesn't care if she dates Vaughn, and she'd actually prefer it. Annie agrees and runs to hug Vaughn.
