The 1946 United States Senate election in Maryland was held on November 5, 1946.

Incumbent Democratic Senator George L. P. Radcliffe ran for a third consecutive term in office, but lost the Democratic primary to Governor of Maryland Herbert O'Conor. O'Conor narrowly defeated Republican D. John Markey to win the open seat.

O'Conor's general election victory and the subsequent recount by a federal Senate Subcommittee were controversial, with each party claiming partisan manipulation by the other.
