James Raymond Creeggan (born February 12, 1970) is the bassist for Canadian alternative rock band Barenaked Ladies.

His mother taught piano lessons to neighbourhood children, which Creeggan credits as part of the reason for his interest in music.

Creeggan, along with his brother Andy, was invited to play with Ed Robertson and Steven Page (then performing as Barenaked Ladies as a duo) at a Christmastime show in Toronto,[3] and the pair was asked to join the band permanently.

Creeggan has also contributed to albums with each of the other members of the violin family, and has orchestrated musical charts for various band instruments to be recorded by session musicians.

Creeggan wrote and sang lead on two songs from the band's 2010 album All in Good Time, "On The Lookout" and "I Saw It", as well as a bonus track titled "She Turned Away".

He also commonly joins artists opening for Barenaked Ladies who do not play with a full band.
