This is a list of the longest team winning streaks in Major League Baseball history. Streaks started at the end of one season are carried over into the following season. Four lists are provided—one with streaks that consist entirely of regular-season games, one with streaks from the predecessor National Association (1871–1875), one with streaks of playoff games only, and one with streaks that include both regular-season and postseason games.

The 1916 New York Giants hold the record for the longest winning streak in MLB history at 26 games, but this streak includes a tie, which is not counted toward official statistics. The longest winning streak not including a tie belongs to the 1935 Chicago Cubs at 21 games. The longest winning streak consisting only of playoff games stands at 12 consecutive wins, by the 1927, 1928 and 1932 New York Yankees (swept the World Series all three seasons) and tied by the 1998-99 Yankees. For streaks that have included both regular and postseason games, the 1970 and 1971 Baltimore Orioles hold the top two positions with 17 and 16 consecutive victories, respectively.
