Kelly Taylor was, for the majority of the show's run, the lead female character of the American television drama Beverly Hills, 90210. Portrayed by actress Jennie Garth, Kelly appears prominently in a majority of the shows which compose the Beverly Hills, 90210 franchise. Introduced in the very first episode in 1990, she would become instrumental in launching the series' first spin-off, Melrose Place, and returned in the third spin-off, 90210.

A survivor of several challenges and perils, Kelly is presented as a young woman who grows from self-absorbed teenage beginnings toward a more sensitive and mature adulthood. Along the way, she gains the romantic attentions of many, but begins to cherish a select few. Having appeared in the most series premieres, as well as the most episodes of any figure throughout the continuity, she is the de facto central character of the Beverly Hills, 90210 franchise.

Throughout the course of the first series, Kelly became one of the show's most developed characters. When introduced, she was presented as a stereotypical spoiled type who placed high value on posh appearances and material possessions.
