Early life The youngest of four siblings, Lennix was born in Chicago, Illinois, to Lillian C. (née Vines), a laundry worker, and Harry Lennix Jr., a machinist.Harry J. Lennix Biography (1965?–) His mother was African-American and his father was Creole from Louisiana.

Lennix attended Quigley Preparatory Seminary South and intended to become a priest. His first play was with the seminary. After a few weeks at seminary, he changed paths to Northwestern University "to pursue a girl", and settled on career choice in drama and majored in Acting and Direction. In his senior year at Northwestern, he was the coordinator of the African-American student organization, For Members Only. Lennix taught music for Chicago Public Schools for eight years. While in school himself and teaching, he commuted two hours between Englewood for teaching and then performances in plays at night. He continued acting training and performed at the Goodman Theatre and Steppenwolf Theatre.

Career 1989–1999 Lennix's first film role was in The Package (1989), which was a Chicago production. Lennix starred in the film Titus (1999), based on Shakespeare's Titus Andronicus, as Aaron the Moor, the secret lover of the Queen of the Goths; in the Showtime Networks television film Keep the Faith, Baby (2002) as reverend and Congressman Adam Clayton Powell Jr.; and in the ABC television series Commander in Chief.

Lennix played Malcolm X in a 1989 production of The Meeting, which earned him an Obie Award. Lennix also performed the play years later. Jack Helbig at the Chicago Reader said about the 1989 performance, "Harry J. Lennix’s uncanny impersonation of Malcolm X went a long way toward redeeming the play. Luckily, Lennix also has the gift of being able to make the most ridiculous lines sound real. “We are all pawns,” he says at one point, somehow convincing us that he is the first person ever to have thought of that."

Lennix also starred as Levee in August Wilson's Ma Rainey's Black Bottom at the Goodman Theater in 1997. The production broke box office records. For a later 2026 production in which Lennix returned to the same play and theatre as musical director, Lennix said:

With Laurence Fishburne he has had numerous conversations and debates about Shakespeare, race, and performance.

On the topic of his Henry IV adaptation H4 and Shakespeare in general, Lennix has said:

2010–present In 2010, Lennix had planned to star in an African-diasporic film version of Macbeth, with director Aleta Chappelle and tentatively also starring Terence Howard, Sanaa Lathan, Blair Underwood, and Danny Glover. Also in 2012, Lennix produced and starred in the lead role in several film productions (see Producer-Actor Projects below) including H4, a modernized Shakespeare film adaptation of Henry IV, Mr. Sophistication which is about a stand-up comedian, and the biblical story Revival!. In Mr. Sophistication (2012), Lennix plays a self-destructive stand-up comedian trying to make a comeback while also having trouble with his interracial marriage. The part was written for Lennix by the director, Danny Green, after Green had observed Lennix dressing someone down. Ebony said that the role resembles the late life of Richard Pryor. Lennix said that the "jerky" personality is based on director Green. As preparation, Lennix studied Lenny Bruce, Dick Gregory, Bernie Mac (who Lennix had seen repeatedly previously in appearances at Milt Trenier's Lounge, a noted cabaret in Chicago), Alonzo Bodden, but mostly Pryor. Lennix had previously done some live improv including with Del Close (of Second City, The Committee, and Saturday Night Live) in the past, but never stand-up comedy. For ten seasons, Lennix co-starred in the role of Harold Cooper, assistant director of the FBI Counterterrorism Division, on the NBC drama The Blacklist (2013–2023).

Lennix participated in the 2014 Chicago Humanities Festival and discussed the book “Black Theater is Black Life: An Oral History of Chicago Theater” with its author, Northwestern University professor Harvey Young. H4 (2012) is an adaptation of William Shakespeare's Henry IV, modernized to a Los Angeles setting while keeping much of the original language. Lennix plays King Henry IV. Keith David and Heavy D also appear. In July 2014, Lennix formed his own production company Exponent Media Group (EMG) along with long time business partner Steve Harris. EMG had a distribution deal with NEHST studios for three of the company's titles: Mr. Sophistication (2012) (see below); H4 in (2012); and Revival! (2018). In 2015, Lennix appeared in Chi-Raq, directed by Spike Lee. Lennix called the film "brave and bold", as it addresses "the violence that’s happening right now in Chicago". Batman v Superman: Dawn of Justice in 2016 featured Lennix reprising the role of Calvin Swanwick from 2013's Man of Steel, both directed by Zack Snyder. Lennix made an additional appearance as Swanwick in Snyder's version of Justice League, released in 2021.

Revival! (2018) is a gospel concert movie that Lennix has described as Jesus Christ Superstar meets The Wiz. Lennix plays Pontius Pilate. Jesus is played by Mali Music. The cast also includes Chaka Khan as Herodia, the wife of Herod, and Michelle Williams of Destiny's Child. Elaine Hegwood Bowen at The Chicago Crusader wrote, "It is magnificent in its vivid, rousing storytelling and vibrant costumes throughout." A review by Jonita Davis at The Black Cape Magazine said the film is "like an Easter reunion for those of us who grew up in the Black pop culture and Black Church" and that it could "finally" replace Charlton Heston’s The Ten Commandments (1956) as the film to watch in the weeks before Easter. Lauren Turner in a review at BRWC wrote, "A constant beat and thump of live music keeps the story moving between more serious scenes, punctuated by musical numbers and dance scenes. We’re not in Nazareth anymore," and said the singing is sometimes "cringe" though the original compositions are good."

During the Chicago Goodman Theater's 2024–2025 season, Lennix played the role of Henry Drummond in the Jerome Lawrence and Robert E. Lee play Inherit the Wind.

Music In 2026, Lennix was the musical director for a production of August Wilson's Ma Rainey's Black Bottom.

Lennix learned to play the trumpet while working on August Wilson’s Ma Rainey’s Black Bottom. He also played the saxophone in a production and has played the piano in other theatrical roles. Northlight Theatre Company director BJ Jones said that Lennix played jazz piano in the rehearsal room during a run of Permanent Collection (2005), and shared Red Garland CDs with him. A 2018 episode of the PBS series The History Makers contains video of Lennix playing piano with a band and singing on stage at an event. In 2005, he played the part of a fictional legendary jazz musician in an episode of House.

Personal life In 2009, Lennix married business executive Djena Graves.

Lennix is a member of the Omega Psi Phi fraternity. He was initiated into the fraternity in November 2012 via the Theta Kappa Kappa graduate chapter in Evanston, Illinois.

Lennix has given multiple college commencement speeches including 2006 at Santa Monica College (speech entitled "Do Not Stop, Do Not Slow Down") and 2008 at Arizona State University (speech entitled "Acting While Black").

Lennix is Catholic.

Community Work Lennix is developing a performing arts center in the Bronzeville of Chicago and has been given $26 million dollars from the state of Illinois for the project, which will include a "Lillian Marcie Center." The facility is planned to include a museum and two performance spaces, one of about 350 seats and one of about 100 seats.
