Kravitz was born on May 26, 1964, in New York City, the only child of NBC television news producer Sy Kravitz (1924–2005) and actress Roxie Roker (1929–1995). His mother came from a Christian family that was of African American and Bahamian descent. His grandfather was Russian-Jewish.^{[disputed – discuss]} Kravitz's paternal grandparents emigrated to the United States from Kiev. Through his mother, Kravitz is a second cousin of television weather presenter Al Roker, as their grandfathers were brothers. Kravitz was named after his uncle, Leonard M. Kravitz, a private first class who was killed in action in the Korean War at the age of 20, while single-handedly holding off a Chinese attack, enabling most of his platoon to escape.

During his early years, Kravitz did not grow up in a religious environment. After a spiritual experience when he was 13, he started attending church and later became a non-denominational Christian. Kravitz grew up spending weekdays on the Upper East Side of Manhattan with his parents, attending P.S. 6 for elementary school, and spending weekends at his grandmother Bessie's house in the Bedford-Stuyvesant neighborhood of Brooklyn.

Kravitz began banging on pots and pans in the kitchen, playing them as drums at the age of three. He decided that he wanted to be a musician at the age of five. He began playing the drums and soon added guitar. He grew up listening to the music his parents listened to: R&B, jazz, classical, opera, gospel, and blues. He said, "My parents were very supportive of the fact that I loved music early on, and they took me to a lot of shows." Around the age of seven, he saw the Jackson 5 perform at Madison Square Garden, and they became his favorite performers. His father, who was a jazz promoter, was friends with Duke Ellington, Sarah Vaughan, Count Basie, Ella Fitzgerald, Bobby Short, Miles Davis, and other jazz greats; Ellington played "Happy Birthday" for him on his fifth birthday.

In 1974, at the age of 10, Kravitz relocated to Los Angeles with his parents when his mother landed her role on The Jeffersons. At his mother's urging, he joined the California Boys Choir for three years, where he performed a classical repertoire, and sang with the Metropolitan Opera. He took part in Mahler's Third Symphony at the Hollywood Bowl. It was in Los Angeles that Kravitz was introduced to rock music, listening to the Beatles, the Rolling Stones, Led Zeppelin, Jimi Hendrix, the Grateful Dead, Aerosmith, Black Sabbath, Creedence Clearwater Revival, Kiss, Pink Floyd, and the Who, and he said he was "attracted to the cool style, the girls, the rock 'n' roll lifestyle." During his junior high school years, he was also introduced to marijuana; he has stated that he was a "pothead" during his youth. His other musical influences at the time included Fela Kuti, Bill Withers, Marvin Gaye, Pharoah Sanders, and Miles Davis. Later influences came in the form of John Lennon and Bob Marley. Kravitz attended Beverly Hills High School, where he was classmates with Maria McKee, Nicolas Cage, and Slash. He taught himself to play piano and bass and made friends with Zoro, who would later become his long-time collaborator. His parents divorced in 1985.

With record labels reportedly telling him his music was not "black enough" or "white enough", Kravitz decided to record an album on his own under the name Romeo Blue. Kravitz had met the recording engineer, keyboardist, and bassist Henry Hirsch in 1985 when recording a demo at his Hoboken, New Jersey, recording studio. The two shared an interest in using real instruments and vintage recording equipment, as well as a love of R&B, jazz, and rock. Kravitz would go on to collaborate with Hirsch on most of his albums. Kravitz began working on his debut album with Hirsch over the next year and a half, with Kravitz's father paying for the studio time. Kravitz met saxophonist Karl Denson and invited him to play on the song "Let Love Rule". Kravitz was so impressed with his playing that Denson played on much of the album. Beginning in the late 1980s, Denson toured with Kravitz for five years.
