Nikki Tyler (born December 4, 1972 in Berkeley, California) is a former pornographic actress best known for her work in the 1990s and for her selection as the December 1995 Penthouse Pet of the Month.
Tyler's first foray into the adult industry was a lesbian scene with Jeanna Fine in the film American Pie (1995). That was followed by another lesbian scene the same year in the film Virtual Reality 69, this time together with Jenna Jameson whom she was living with at the time.    Tyler and Jameson had previously met during a Suzi Randall photo shoot and Jameson recounts in her autobiography that the two of them "hit it off immediately". Tyler would later become Jameson's mentor in the industry for a while.  She became Penthouse magazine's Pet of the Month in December 1995. After her Vivid contract, she went on to work for companies such as Wicked Pictures and Adam & Eve.  According to IAFD, her last film was in 2003. 
Tyler was in an off-screen lesbian relationship with porn actress Jenna Jameson.  The couple lived together for a number of years before they separated.  Jameson continued to see Tyler even during the period when she got involved with Jay Grdina. Tyler retired from the industry in the early 2000s. As of 2004, she is living with her husband and daughter in California.
