Brian Douglas Wilson (June 20, 1942 — June 11, 2025) was an American musician, singer, songwriter, and record producer who co-founded the Beach Boys. After signing with Capitol Records in 1962, Wilson wrote or co-wrote more than two dozen Top 40 hits for the group. He originally functioned as the band's songwriter, producer, co-lead vocalist, bassist, keyboardist, and de facto leader.

Wilson was considered a major innovator in the field of music production, the principal originator of the California Sound, one of the first music producer auteurs, and the first rock producer to use the studio as its own instrument. The unusual creative control Capitol gave him over his own records effectively set a precedent that allowed other bands and artists to act as their own producers or co-producers. He was a major influence on the retrospectively-termed "sunshine pop" and Flower Power music that proceeded.
