List of National League pennant winners

This team receives the Warren C. Giles Trophy and the right to play in the World Series against the champion of the American League (AL).

The trophy is named for Warren Giles, the league president from 1951 to 1969, and is presented immediately after each NL Championship Series (NLCS) by Warren's son Bill Giles, the honorary league president and former owner of the Philadelphia Phillies.

The pennant has been awarded every year since 1876, except for 1994, when a players' strike forced the cancellation of the postseason.

[6] In 1995, an additional playoff series was added when MLB restructured the two divisions in each league into three.

There was an earlier "World's Championship Series" played between the pennant winners of the NL and the American Association 1884–1890; from 1894 to 1897 the NL's first- and second-place teams played a postseason series for the Temple Cup, which was considered to be the league championship.
