"Who Shot Ya?" is a song by American rapper the Notorious B.I.G., backed by Sean Combs. Bad Boy Entertainment released it on February 21, 1995, on an alternate reissue of Wallace's single "Big Poppa/Warning". Its new B-side "Who Shot Ya", a revision of a track already issued earlier in 1995, was "controversial and hugely influential." Widely interpreted as a taunt at Tupac Shakur, the single provoked a "rap battle" between the two rappers, formerly friends.
