Kevin Neil Hearn (born July 3, 1969 in Grimsby, Ontario, Canada) plays keyboards and other instruments for Barenaked Ladies and also has his own band, Kevin Hearn and Thin Buckle. He attended Inglenook Community High School.

Kevin was born to a relatively large family, and they lived in a small home. He recalls buying Magical Mystery Tour and a Beach Boys greatest hits record, and having them become his first two favourite albums, which led him to an interest in performing music. Hearn has a classical piano background. He also attended St. Michael’s Choir School.

Hearn currently lives in downtown Toronto. He also spends time at a cottage which he acquired in the early 2000’s. The isolated cottage is on a lake where his family spent time when he was a child.

Hearn’s cousin is actor and comedian Harland Williams, with whom he spent a lot of time as a child.

Hearn joined The Look People in 1988 and played with the band until their break-up in 1993. In 1995 he replaced departed keyboardist Andy Creeggan in the Barenaked Ladies. Hearn did not own any of the band’s albums and had to learn all of the band’s songs in a matter of weeks.

His early contribution to the band can be heard on the live release Rock Spectacle, which was recorded on his first tour with the group. He played mostly keyboards on the songs included on the album, and some accordion. His first BNL music video was the video for "Shoe Box", followed by the video for "The Old Apartment". Also, thanks to the opportunities afforded him by the job, Hearn released an album called Mothball Mint of his own material.

After extensive touring in the United States, building upon increasing success of Rock Spectacle, the band recorded their fourth studio album, Stunt. This was Hearn’s first album with the band. While Andy Creeggan was mostly focused on acoustic keyboards, Hearn was experienced with electronic keyboards, synthesizers and samplers. This contribution to the band’s sound is evident on Stunt. Hearn also contributed some lead electric guitar to the album, having a noticeably different style than Ed Robertson or Steven Page.
