Dillinger (born Lester Bullocks on January 25, 1953) is a prominent reggae artist. Dillinger was part of the second wave of DJ Toasters who sprung up around Jamaica during the mid 1970s. Inspired by Big Youth, U Roy, and Dennis Alcapone, Dillinger was known for his quick wit, humorous lyrics and vulgar content ("crab in my pants").

As a youth growing up in Kingston, Jamaica, Dillinger would hang around Dennis Alcapone's El Paso Setup. This exposure would eventually lead to a full time gig at Jackie's sound system. Just as Alcapone took his performing name from a famous American gangster, Dillinger took his own name from John Dillinger.

The song "Cocaine In My Brain" is considered an all-time reggae classic and was even featured on the K-Jah reggae station of GTA: San Andreas.
