2022 United States Senate election in Maryland

The 2022 United States Senate election in Maryland was held on November 8, 2022, to elect a member of the United States Senate to represent Maryland. The Democratic and Republican primaries were held on July 19, 2022.

Incumbent Democratic Senator Chris Van Hollen was first elected in 2016 with 60.9% of the vote, winning the seat of retiring incumbent Barbara Mikulski. He ran for a second term against Chris Chaffee, the Republican nominee.

Shortly after polls closed on November 8, 2022, the Associated Press called the race for Van Hollen. He overperformed his 2016 numbers and flipped four counties that he lost in his first election: Anne Arundel (home to the state capital Annapolis), Frederick, Kent, and Talbot.
