Beverly Hills, 90210 (franchise)

The Beverly Hills, 90210 franchise comprises the ongoing timeline and shared characters that link the American television series Beverly Hills, 90210 (1990); Melrose Place (1992); Models Inc. (1994); 90210 (2008); Melrose Place (2009); and the 2019 revival BH90210, which takes place outside of the franchise continuity.

The continuity, which progresses in real time, was introduced in 1990 with the debut of Darren Star's teen drama Beverly Hills, 90210, which was produced by Aaron Spelling and initially aired on the FOX television network in the United States. After this series became a worldwide success in 1991, Star expanded the franchise with 1992's Melrose Place, a drama about young adults in Los Angeles. The third series, Models Inc., aired from June 1994 to March 1995.

The fourth entry, simply titled 90210, was developed by Rob Thomas, Gabe Sachs, and Jeff Judah, and premiered on The CW on September 2, 2008. On September 8, 2009, the fifth series, a follow-up to Melrose Place, also debuted on The CW, and concluded in April 2010.

The franchise has been generally well received among young audiences. Some characters have appeared in multiple shows throughout the continuity. Jennie Garth, Tori Spelling, Brian Austin Green, and Ian Ziering are the only actors who appeared in a show's entire run, while Grant Show appeared in all three of the original series.

In February 2019, it was announced that a six-episode revival, set outside of continuity, had been ordered by FOX and that the show would be titled BH90210. The series aired between August and September 2019.
