Adi Marie Roche (born 11 July 1955) is an Irish activist, anti-nuclear advocate, and campaigner for peace, humanitarian aid and education.

In 1990, she became the first Irish woman elected to the board of directors of the International Peace Bureau at the United Nations in Geneva.

Entitled Black Wind, White Land, the exhibition was a month-long, cross-cultural event featuring the works of artists who depicted the suffering caused by the disaster.

Roche has provided advice and suggestions to the UN Needs Assessment Mission and has made several submissions on how NGOs could best be helped in their attempts to deliver humanitarian aid to the most affected areas in Belarus, Ukraine and western Russia.

In July 2003, she was the keynote speaker at the launch of the International Chernobyl Research and Information Network (ICRIN) in Geneva, Switzerland.

To mark the 18th Anniversary of the tragedy in April 2004, Roche was invited to speak at the UN General Assembly at their headquarters in New York and to screen the Oscar award-winning documentary Chernobyl Heart.

On 26 April 2016, the 30th anniversary of the Chernobyl disaster, Roche made a landmark address to the United Nations General Assembly in New York.
