Connecticut's 26th State Senate district elects one member of the Connecticut State Senate. The district consists of the entirety of Westport, Wilton, Ridgefield, and Redding, and parts of Bethel, New Canaan and Weston. Previously, the 26th district comprised Norwalk, Wilton, New Canaan, and Easton. However, in the late 1970s Norwalk and Darien became the 25th district. It is currently represented by Democrat Ceci Maher since 2023.
At some point shortly prior to 1905, Connecticut was redistricted. Fairfield County was previously represented in the 12th Senate District.
