Chase (née Mayfield,[1][2] born January 6, 1942) is a former Democratic member of the Washington State Senate, representing the 32nd district from 2011 to 2019.

In 1997, Chase became an associate of Women's Institute for Freedom of the Press (WIFP).

The organization works to increase communication between women and connect the public with forms of women-based media.

Chase was appointed by the legislature after Representative Carolyn Edmonds resigned in November 2001 to serve on the King County Council.

An amendment added to Senate Bill 5575 by Maralyn Chase added a Georgia-Pacific paper mill in Camas, WA to the list of pre-1999 biomass facilities that may generate renewable electricity.
