Wendy Russell Davis (born Wendy Jean Russell; May 16, 1963) is an American lawyer and Democratic politician from Fort Worth, Texas. Davis represented District 10 in the Texas Senate from 2009 to 2015. She previously served on the Fort Worth City Council.
On June 25, 2013, Davis held an eleven-hour-long filibuster to block Senate Bill 5, a measure which included more restrictive abortion regulations for Texas. The filibuster played a major role in Senate Democrats' success in delaying passage of the bill beyond the midnight deadline for the end of the legislative session, though it ultimately passed in a second session. The filibuster brought Davis national attention, leading to speculation about a run for governor. She subsequently ran for governor in 2014 but lost to Greg Abbott, 59–38 percent.
