Nancy Alaan Catamco is a Filipina politician and the incumbent governor of the Province of Cotabato.

As a congresswoman, Catamco was involved in the advocacy for the rights, interests, and concerns of Indigenous peoples in the House of Representatives.

During her term as representative, she authored and co-authored bills related to education, agriculture, labor, health, senior citizens, women and youth.

On July 4, 2019, the Supreme Court of the Philippines suspended Catamco as North Cotabato governor for 90 days as she was facing graft and malversation charges relating to allegedly supplying overpriced fertilizers to the town of Poro, Cebu in 2004.

She continued her post-graduate studies with units in guidance and counselling from the Alliance Graduate School.
