V-Day is a global movement to end violence against women and girls inspired by Eve Ensler's play, The Vagina Monologues. The movement was started in the late 1990s by author, playwright and activist Eve Ensler. Ensler has been quoted as saying that it was women's reactions to the play that launched V-Day. After seeing The Vagina Monologues, women would line up after to tell Eve their personal experiences, most often of sexual violence.

There are two types of V-Campaigns:

The College Campaign and the Community Campaign.

The V-Day College Campaign engages members of college and university communities around the world to present benefit productions of The Vagina Monologues, A Memory, A Monologue, A Rant and A Prayer. Until the Violence Stops, Any One of Us, and What I Want My Words to Do to You on their campuses to raise money and awareness to stop violence against women and girls.

The V-Day Community Campaign invites communities around the world to present productions of The Vagina Monologues, A Memory, A Monologue, A Rant and A Prayer, Until the Violence Stops, Any One of Us, and What I Want My Words to Do to You to raise money and awareness to stop violence against women and girls.

Each year V-Day spotlights a particular group of women who are experiencing violence with the goal of raising awareness and funds to put a worldwide media spotlight on this area and to raise funds to aide groups who are addressing it. The 2009 spotlight focuses on the women and girls from the Democratic Republic of Congo.
