Femmeslash (also known as femslash, girlslash, yuri, or shoujo-ai) is a variation on the traditional definition of slash -- homosexual/homoerotic/homoromantic fanfiction. Femmeslash is, essentially, putting female characters together in a romantic and/or sexual relationship.

Femmeslash is generally considered to be rarer than male/male slash, but there have been more and more fandoms that are femmeslash-positive, including Harry Potter, ER, Buffy the Vampire Slayer, and, the first primarily femmeslash fandom, Xena: Warrior Princess, as well as making headways into the older, more well-known fandoms, such as Star Trek, The X-Files, and comic books.

Femmeslash is a wide and varied genre, ranging from epic romances to hardcore pornography to lighthearted romps to darkest horror. Also varied is its audience—while it may seem that the ideal audience for femmeslash is a purely heterosexual male audience (as most female/female pornography is geared towards the male viewer), femmeslash has a very strong and outspoken female audience.
