Frasier Winslow Crane is a fictional character on the American television sitcoms Cheers and Frasier, portrayed by Kelsey Grammer. Grammer received award recognitions for portraying this character in these two shows, in addition to a 1992 one-time appearance in Wings.

The character debuts in the Cheers third season premiere, "Rebound (Part 1)" (1984), as Diane Chambers's love interest, part of the Sam and Diane story arc. Intended to appear for only a few episodes, Grammer's performance for the role was praised by producers, prompting them to expand his role and to increase his prominence. Later in Cheers, Frasier is married to Lilith Sternin (Bebe Neuwirth) with a son, Frederick, and resides in Boston. After Cheers ended, the character moved to his spin-off series Frasier, the span of his overall television appearances therefore totaling twenty years. In the spin-off, Frasier moves back to his birthplace Seattle after his divorce from Lilith, who retained custody of Frederick in Boston, and is reunited with a newly created family: his estranged father Martin and brother Niles. In the series finale, he is supposed to depart to San Francisco for his proposed talk show, but instead he goes to Chicago, where one of his love interests resides.
