Lawrence Joseph Mullen Jr. (/ˈmʊlən/; born 31 October 1961) is an Irish musician and actor, best known as the drummer and co-founder of the rock band U2.

A member of the band since its inception, he has recorded 14 studio albums with U2. Mullen has worked on numerous side projects during his career. In 1990, he produced the Ireland national football team's song "Put 'Em Under Pressure" for the 1990 FIFA World Cup. In 1996, he worked with U2 bandmate Adam Clayton on a dance re-recording of the "Theme from Mission: Impossible". Mullen has sporadically acted in films, most notably in Man on the Train (2011) and A Thousand Times Good Night (2013).
