Ashley Judd is set to be honoured at the Greenwich International Film Festival (GIFF) for her dedication to her humanitarian work.

The 49-year-old actress will be given the Changemaker Award at the festival's 4th annual gala on May 31, in Greenwich, Connecticut, for helping women and children around the world through her work as a Goodwill Ambassador for the United Nations Population Fund (UNFPA).

In a statement, Ashley said: ''It is an honour to have been chosen as a Changemaker Award recipient at the 2018 Greenwich International Film Festival. The festival serves as a great example of how film can be elevated to affect social change, and I'm grateful to be a part of such an extraordinary community.''

The 'Heat' actress has been working with UNFPA since 2016, and has travelled to countries including Jordan, Ukraine, Turkey, India and most recently Bangladesh, to help improve the lives of women and children.

GIFF Chairman of the Board, Wendy Stapleton Reyes, said: ''We are incredibly honored to have Ashley Judd as our 2018 Changemaker. She is an unapologetic voice for equality and women's rights throughout the world. Ashley serves as an incredible example of an individual who, despite the consequences, has refused to be silenced when she has been confronted by injustice and has therefore eased the path for the next generation.''

The Changemaker award - which is bestowed upon artists who have used ''their public platform and the power of film to further positive social change'' - has existed since 2014, and previous honourees include Renee Zellwegger, Mia Farrow, Freida Pinto, Trudie Styler and Abigail Breslin.

For Ashley, the award comes after she was named as one of Time magazine's People of the Year in 2017 for being a ''silence breaker'', after she was one of the first people to come forward and accuse disgraced producer Harvey Weinstein of sexual harassment.

The 'Divergent' star is also the global ambassador for Population Services International and Polaris, which is working to eradicate human trafficking.
