He graduated from Evanston Township High School and attended Harand Theater Camp in Elkhart Lake, Wisconsin, as a teenager. He played the part of "Bernardo" in 'West Side Story' there. In Illinois, he trained at Piven Theatre Workshop, founded by his parents, Byrne Piven and Joyce Piven, both of whom were actors and drama teachers.

He has appeared in a number of films with John Cusack, who is also from Evanston and is a fellow alumnus of the Piven Theatre Workshop (as are Cusack's sisters Joan and Ann). Piven and Cusack once shared an apartment and have been friends since high school.

Piven's first significant role came in 1992 when he became a regular cast member on HBO's 'The Larry Sanders Show,' where he played the head writer Jerry. In 1993, he portrayed George Costanza on the show-within-a-show scene in the 'Seinfeld' episode, "The Pilot". Piven has appeared in several successful films, including 'Lucas', 'Grosse Pointe Blank', 'Singles', etc.

Since 2004, Piven has reinvigorated his career by playing a fast-talking, acerbic Hollywood agent Ari Gold in the HBO series 'Entourage'. He received Emmy nominations for best supporting actor four straight years from 2005 to 2008, and won the award in 2006, 2007, and 2008. 2009 was the first year in which he did not receive an Emmy Award nomination for his work on Entourage. Piven was also the star and producer of the short-lived ABC dramedy series Cupid, and was a supporting cast member on the last three seasons of the sitcom Ellen. He played the part of Ellen's cousin, Spence. He also voiced Elongated Man in three episodes of Justice League Unlimited.

In 2007, Piven appeared in the video for "Drivin' Me Wild", the third single taken from rapper Common's seventh album Finding Forever. The two were co-stars in Smokin' Aces, and appeared together when Piven hosted SNL in January 2007.

Piven appeared in the first Broadway revival of David Mamet's Speed-the-Plow, co-starring Mad Men star Elisabeth Moss and three-time Tony nominee Raul Esparza. The production began preview performances on October 3, 2008, and opened on October 23, 2008; the play was due to run through February 22, 2009.

After Piven missed several performances, on December 17, 2008, Piven's rep announced that due to an undisclosed illness, Piven would be ending his run in the play effective immediately. The illness was revealed to be hydrargaria, a disease caused by exposure to mercury or its compounds, though the source is unknown. Rumours have indicated that the high level of mercury could potentially have been caused by Piven's habit of consuming fish twice a day for the past 20 years. An alternative explanation is that the herbal remedies Piven was taking were responsible for his high levels of mercury. Mamet joked that Piven was leaving the play "to pursue a career as a thermometer." On September 1, 2009, Piven, in a guest appearance on Late Show with David Letterman, explained that he had given up red meat and poultry and had been getting all of his protein from fish for the past 20 years.

Piven considers himself a Jewish Buddhist. He starred in the Travel Channel special 'Jeremy Piven's Journey of a Lifetime' detailing his journey across India.
