UNIFEM's Say NO initiative is a global platform for advocacy and action, contributing towards the objectives of the UN Secretary-General Ban Ki-moon's campaign UNiTE to End Violence against Women through social mobilization.

On 25 November 2008, Say NO presented more than 5 million signatures to the UN Secretary-General, demonstrating public support to make ending violence against women a top priority for governments everywhere.

The next chapter of Say NO, launched on 6 November 2009, will collect and demonstrate actions from individuals, organizations and decision-makers everywhere.
