The Texas House of Representatives' 66th district represents a portion of Collin County, including parts of Plano and Dallas. The current representative of this district is Matt Shaheen, a Republican from Plano who has represented the district since 2015.
Upon being moved to Collin County in 1993, district 66 became a suburban Republican stronghold; recently however, the district has become increasingly competitive, with Democrats coming within 1 percentage point of flipping the district in both 2018 and 2020.
As a result of the 2021 redistricting, the district will represent parts of Frisco, Plano, Prosper, and Celina.
