Loveline is a syndicated radio call-in program in North America, offering medical and relationship advice to listeners, often with the assistance of guests, typically actors and musicians. Its host through most of its run was Dr. Drew Pinsky who was paired with a radio personality.

Loveline was broadcast live, Sundays through Thursdays at 10pm–midnight PT (Mondays through Fridays at 1am–3am ET). Its flagship station was KROQ-FM in Los Angeles. Syndication was usually on rock, alternative, and adult talk radio stations. Loveline can also be heard online anywhere in the world, by streaming through the websites of affiliate stations.

The radio show was discontinued in April 2016. After a hiatus, the show was rebooted as a podcast with Amber Rose and clinical psychologist and sex therapist, Chris Donaghue, as hosts. The renewed podcast ran from September 8, 2016, until March 17, 2018.

On November 1, 2018, Loveline was revived on LGBTQ network Channel Q with Dr. Chris Donaghue as the solo host, heard Monday through Thursday from 7 to 9 p.m. Eastern Time. Channel Q is owned by Audacy, Inc. and heard on the company's namesake streaming service and on the HD Radio subchannels of about 20 FM stations in New York City, Los Angeles, Chicago and other large media markets.

During its peak of popularity, Loveline also doubled as a weekly live audience television program on MTV, also called Loveline. It was presented by Pinsky, Adam Carolla and a third co-host.
