Lookout Records (stylized as Lookout! Records) was an independent record label, initially based in Laytonville, California, and later in Berkeley, focusing on punk rock. Established in 1987, the label is best known for having released Operation Ivy’s only album, Energy, and Green Day's first two albums, 39/Smooth and Kerplunk.

Following the departure of co-founder Larry Livermore in 1997, the label departed from its "East Bay sound" and proved unable to match early success. In 2005 the label ran into financial difficulties after several high-profile artists rescinded the rights to their Lookout Records material. After a period of rapid contraction the label slowly expired, terminating operations and removing its music from online distribution channels early in 2012.
