Wytony Dillon (born 30 December 1973), better known by his stage name Big Wy, is an American rapper from Inglewood, California. Wy (then known as Red Rag) made his debut in 1993 as a member of Bloods & Crips on the album Bangin' on Wax. While still a member of the group, Wy formed Young Soldierz, who released their self-titled debut in 1994. Wy later joined the Bloods-formed Damu Ridas, and recorded the album How Deep Is Your Hood with the group in 1999.

After the dissolution of the Bloods & Crips and its affiliated projects, Big Wy formed the duo The Relativez with former Young Soldierz member Suga Buga. The Relativez released three albums from 2000 to 2007. After a short period of musical inactivity, Big Wy came to prominence after forming the group Cali Swag District in 2010, who achieved international success with their single “Teach Me How to Dougie” that same year.
