The 1948 Illinois gubernatorial election took place on November 2, 1948.^[1] Incumbent Governor Dwight H. Green, a Republican seeking a third term, lost reelection to Democratic nominee Adlai Stevenson II.

The primaries and general election both coincided with those for federal offices (United States President, House, and United States Senate) and those for other state offices. The election was part of the 1948 Illinois elections.^[1]

At the time, Illinois was a predominantly Republican-leaning state.^[2] The state had only elected three Democratic governors since the American Civil War.^[2] Stevenson defeated Green in what was regarded as a surprise upset. His margin of victory of 572,067 votes was, at the time, record-breaking for an Illinois gubernatorial election.^[2][3][4][5]

Stevenson's strong performance in the gubernatorial election and Democratic nominee Paul Douglas' strong performance in the 1948 United States Senate election in Illinois were regarded as having helped the Democratic ticket of Harry S. Truman and Alben W. Barkley secure their narrow victory in Illinois in the 1948 United States presidential election.^[5][6]
