Niles Crane (born 1957) is a fictional character on the American sitcom Frasier, a spin-off of the television show Cheers. He was portrayed by David Hyde Pierce. Niles is the younger brother of Frasier Crane (played by Kelsey Grammer). Pierce was hired because Frasier producers saw his headshot and commented on how much he looked like a young Grammer. Unlike Frasier, part of whose background comes from Cheers, Niles's background is established over the course of Frasier.
