The 1963 National Football League Championship Game was the 31st annual championship game, played on December 29 at Wrigley Field in Chicago, Illinois. The game pitted the visiting New York Giants (11–3) of the Eastern Conference against the Chicago Bears (11–1–2) of the Western Conference.

Originally, NFL Commissioner Pete Rozelle asked Bears owner/coach George Halas to move the game to Soldier Field for its higher seating capacity and lights, as the game could extend into multiple overtime periods. (Wrigley Field was not lighted until 25 years later, in 1988.) Soldier Field was the home field of the Chicago Cardinals in 1959, and became the home of the Bears in 1971.

When Halas refused, Rozelle moved the game's starting time up an hour to 12:05 p.m. CST for increased daylight, similar to 1960 at Franklin Field. The championship game was played in temperatures under 10 °F (−12 °C).

The Giants were in their third consecutive championship game and fifth in the last six seasons. They lost to the Baltimore Colts in 1958 and 1959 and the Green Bay Packers in 1961 and 1962. The Bears were in their first championship game since a loss to the Giants in 1956 at Yankee Stadium, and had last won in 1946, over the Giants at the Polo Grounds.
