Two of a Kind is an American sitcom that aired on ABC as part of the network's TGIF line-up, starring Mary-Kate and Ashley Olsen in their first television series since Full House ended in 1995. The show aired from September 25, 1998, to July 9, 1999.

TGIF was an American prime time television programming block that has aired on ABC at various points since the late 1980s. The name comes from the initials of the popular phrase "Thank God It's Friday"; however, the stars of the lineup touted the initialism meaning "Thank Goodness It's Funny." In its various incarnations, the block mainly featured situation comedies aimed at a family audience, and served as a lead-in to the long-running newsmagazine 20/20.
