Doris Soliz (born 2 March 1958) is an Ecuadorian politician who has been a Government minister and Executive Secretary of Alianza País.

In 2011 in the power struggle that saw Rafael Correa take over the leadership of the Alianza Pais party, a National board was created.

Soliz was one of the 22 members of that board which included Irina Cabezas, Nancy Morocho, María Luisa Moreno, Dora Aguirre, Jorge Loor, Gabriela Rivadeneira and Patricia Sarzoza.

She started drawing up lists of militants which was in line with previous position that the President Rafael Correa had made.

Doris Soliz, María Soledad Buendía, Edwin Jarrín and Ítalo Centanaro who had been part of Rafael Correa's government were asked to comment on information that had come to light from a computer that had belonged to Laura Ternan when she was an assistant to the Presidency of the Republic.
