Timothy John Ryan is an American politician who served as a U.S. representative for Ohio from 2003 to 2023. A member of the Democratic Party, he represented Ohio's 13th congressional district from 2013 to 2023, having previously represented Ohio's 17th congressional district from 2003 to 2013. Ryan's district included a large swath of northeastern Ohio, from Youngstown to Akron. He was the Democratic nominee in the 2022 United States Senate election in Ohio.

The 13th congressional district of Ohio is represented by Representative Emilia Sykes. Due to reapportionment following the 2010 United States census, Ohio lost its 17th and 18th congressional districts, necessitating redrawing of district lines. Following the 2012 elections, the 13th district changed to take in much of the territory in the former 17th district, including the city of Youngstown and areas east of Akron.
