 The 2022 Maryland Senate election were held on November 8, 2022, to elect senators in all 47 districts of the Maryland Senate. Members were elected in single-member constituencies to four-year terms. These elections were held concurrently with various federal and state elections, including for Governor of Maryland. The Democratic and Republican primaries were held on July 19, 2022.
 Democrats gained 2 seats, increasing their supermajority to 34 out of 47 seats.  Simultaneously with gains in the state house and Wes Moore's win in the gubernatorial race,  Democrats won a trifecta in the state for the first time since 2010. 
 The Democratic Party had held majority control of the Senate since the beginning of the 20th century. The closest that the Republican Party had come to gaining control since then was in 1918, when Democrats held a thin 14 to 13 majority. Although Republicans had controlled the governorship since 2015, Democrats maintained a veto-proof supermajority of three-fifths in the 2014 and 2018 elections.
 In the 2022 elections, Governor Larry Hogan was term-limited and Democrats assembled a large field of candidates to reclaim the office. The party retained their majority in the General Assembly and successfully retook the governor's office, and re-established a government trifecta.
