Catfish Collins (born Phelps Collins) is a rhythm guitarist mostly known for his work in the P-Funk collective. Although frequently overshadowed by his brother, Bootsy Collins, Catfish played on many important and influential records by Parliament, Funkadelic, and Bootsy's Rubber String Band.

In 1968, Catfish and his brother, along with Kash Waddy and Philippe Wynne, formed a group called The Pacesetters, better known as The JB's, James Brown's backing band.

In 1972, Catfish and the rest of the JB's joined Funkadelic. In 1976, Catfish joined Bootsy's Rubber String Band, which included Waddy, Joel "Razor Sharp" Johnson (keyboards), Gary "Muddbone" Cooper (drums), and Robert "P-Nut" Johnson (vocals), along with The Horny Horns. Catfish has also played on albums by Deee_Lite, Freekbase, and H-Bomb.
