Anthony Rapp

In November 2019, Rapp announced his engagement to his partner, Ken.

In late October 2017, Rapp alleged in an interview with BuzzFeed that actor Kevin Spacey made an unwanted sexual advance toward him in 1986, when Rapp was 14 and Spacey was 26. At the time, Rapp and Spacey were both appearing in Broadway shows – Rapp in Precious Sons, Spacey in Long Day's Journey into Night – and Spacey invited Rapp to a party at his home. At the end of the evening, an apparently drunk Spacey picked up Rapp, placed him on a bed and attempted to initiate sex. Rapp added that he had once allegedly met with a lawyer to discuss possible legal action, but was told there was no case worth pursuing. He had previously discussed the assault in a 2001 interview with The Advocate, but Spacey's name was redacted from publication to avoid legal disputes and public outing. Rapp was inspired to come forward in 2017 after the effects of the Harvey Weinstein sexual abuse allegations with the support of his family, boyfriend, and representatives.

Rapp is a "die hard" Chicago Cubs fan and co-hosts the podcast The Clubhouse about baseball. At the Cubs game on August 29, 2016, he threw the first pitch and sang the Star Spangled Banner. He enjoys playing poker and video games.

Rapp played the role of Lucas in If/Then, which starred fellow Rent alum Idina Menzel. If/Then played the National Theatre in Washington, D.C., and began previews on Broadway on March 5, 2014, and opened on Broadway at the Richard Rodgers Theater on March 30, 2014. In July, Rapp had to miss performances due to a knee injury and surgery. It closed on March 22, 2015. Rapp reprised the role in the 2015-2016 National Tour, along with Menzel and the rest of the main Broadway cast.

Rapp also appeared in "Psych: The Musical", an episode of the TV series Psych, which premiered on USA Network on December 15, 2013. In 2016, Rapp was cast in Star Trek: Discovery as Lt. Commander Paul Stamets, the first openly gay character in the Star Trek television series. This was Rapp's first television regular role; while he had watched some Star Trek as a child, he watched "curated lists" of episodes from the multiple series to prepare for the role.

In 2000, Rapp released a solo CD, entitled Look Around. In 2006, he published a memoir about Rent and his relationship with his mother, Without You: A Memoir of Love, Loss, and the Musical Rent. The manuscript took him six years to finish because of how personal it was. Rapp developed a one-man stage show with music based on the memoir beginning in 2007, later performing it at such locations as the Edinburgh Festival Fringe. A recording of the show was released on December 11, 2012, by PS Classics.

In 2012, the periodical Metro Weekly referred to Rapp as "one of the first openly gay men on Broadway". He first came out to his mother at the age of 18, and by her death in 1997 she had grown comfortable with it. During a 1997 interview with Oasis magazine, the actor explained his sexual identity as "queer" rather than "gay":

Rapp went on to play the character of Mark Cohen in the off-Broadway and original Broadway casts of Jonathan Larson's musical Rent. For his audition, Rapp sang R.E.M.'s "Losing My Religion", and received his callback in September 1994. After offering him the role, Jonathan Larson wrote new songs for the production with Rapp's voice in mind. He reprised that role in the film adaptation, which was released on November 23, 2005. He returned to Rent on July 30, 2007, for a six-week run, along with original cast member Adam Pascal. The two continued in their return to Rent through October 7, 2007. Rapp and Pascal, along with fellow original cast member Gwen Stewart, reprised their roles of Mark and Roger in a national tour of Rent beginning January 6, 2009.

In 2005, Rapp played the doctor in the world premiere of Feeling Electric (later to become the Broadway musical Next to Normal) at the New York Musical Theatre Festival. During Next to Normal's Off-Broadway run (2008), he worked as assistant director to Michael Greif, who had directed him in Rent, and later wrote the introduction to the published script.

Rapp had a close relationship with his mother, who was battling cancer during the beginning of the Off-Broadway and Broadway transfer of Rent. He would visit her on weekends. She died at age 55 in 1997. He credits her for instilling values of justice and respect in him by leading by example.

Rapp participated in community theater as a child and won awards for his singing in junior high school. Rapp attended high school at Joliet West High School and theatre camp at Interlochen Arts Camp in Michigan. He moved to New York in 1989 to attend New York University as a film student, but dropped out after a semester. Rapp has been a friend of comic Andy Dick since childhood.

Rapp first performed on Broadway in 1981 in The Little Prince and the Aviator, a musical based on Antoine de Saint-Exupéry's novel The Little Prince. The show closed during previews. His screen debut was as a member of the starring ensemble in the 1987 film Adventures in Babysitting, directed by Chris Columbus, who would later direct him in the film version of Rent. He has appeared in several movies and Broadway shows. His notable roles include such films as Dazed and Confused, A Beautiful Mind, School Ties, Road Trip, Six Degrees of Separation (stage and film versions), An American Family, Danny Roane: First Time Director, and You're a Good Man, Charlie Brown.
