1948 United States presidential election in New Mexico

The 1948 United States presidential election in New Mexico took place on November 2, 1948. All 48 states were part of the 1948 United States presidential election. State voters chose four electors to represent them in the Electoral College, which voted for President and Vice President.

New Mexico was won by incumbent President Harry S. Truman, who took the Oval Office after the death of President Franklin D. Roosevelt. Running against Truman was Governor of New York Thomas E. Dewey, who was strongly predicted to win the contest. Dixiecrat candidate Strom Thurmond took portions of the South, but was not even on the ballot in New Mexico and other Western states.
