"Who Shot Ya?," or often, without the question mark, "Who Shot Ya," is a song by gangsta rapper The Notorious B.I.G., commonly called Biggie Smalls, backed and produced by Puff Daddy. It was released by Puffy's emerging record label, Bad Boy Records, on February 21, 1995, on the B side of an alternate reissue of Biggie's single "Big Poppa/Warning," out since December 5, 1994. While the A side's "Big Poppa" was already a big pop hit, the reissue's closing track, "Who Shot Ya?"—with menacing lyrics delivered deftly—swiftly became a massive hit on the streets, and highly influential. Biggie's most infamous classic, it was also controversial. Despite never naming him, it started a "rap battle" with rapper Tupac.
