David Chase (born August 22, 1945) is an American screenwriter, director, and television producer. Chase has worked in television for more than 30 years; he has produced and written for shows as The Rockford Files, I'll Fly Away, and Northern Exposure. He has created two original series; the first, Almost Grown, aired for 10 episodes in 1988 and 1989. Chase is best known for his second original series, the influential and critically acclaimed HBO drama The Sopranos, which aired for six seasons between 1999 and 2007. A prominent figure in American television, Chase has won seven Emmy Awards.

An only child, David DeCesare was born to Henry and Norma DeCesare (both of Neapolitan origin) in Mount Vernon, New York. Some sources list his birth name as David Del Cesare. An Italian-American, Chase grew up in a small garden apartment in Clifton, New Jersey and in North Caldwell. Chase has stated that he had many issues with his parents—who he feels were overbearing—as a youth. He grew up watching matinée crime films and was well-known as a creative storyteller during his childhood. Chase claims his father was an angry man who belittled him constantly as a child and his mother was a "passive-aggressive drama queen" and "a nervous woman who dominated any situation she was in by being so needy and always on the verge of hysteria. You walked on eggshells." One of his characters on the HBO original series The Sopranos, Livia Soprano is based on his mother. Chase struggled with severe depression as a teenager, something he still deals with today. He graduated from high school in 1964 and attended Wake Forest University in Winston-Salem, North Carolina, where his depression worsened. "I slept 18 hours a day," Chase later stated. He described his problems as "what's come to be known as normal, nagging, clinical depression. It was awful." He also worked as a drummer during this period, and held aspirations of being a professional musician. After two years, he transferred to New York University (NYU), where he announced his decision to pursue a career in film, a decision that was not well-received by his parents. He went on to attend Stanford University's School of Film.

After graduating from NYU in 1968 Chase moved to California and married his high school sweetheart Denise Kelly.
