The franchise's first manager was John Clapp, who managed the team for one year before being replaced in 1884 by Jim Price. The New York Giants won two World Series championships during the 19th century, in 1888 and 1889, with Jim Mutrie as their manager both years.{{ref label|Mutrie|a|a}} John McGraw became the Giants' manager during the 1902 season, beginning a streak of 54 consecutive years in which the Giants were managed by a Baseball Hall of Famer. McGraw managed for the better course of 30 years (he missed parts of the 1924, 1925, and 1927 seasons due to illness; Hughie Jennings took over for the former two while Rogers Hornsby served as player-manager for the latter), doing so until the middle of the {{mlby|1932}} season, the longest managerial tenure in Giants history. McGraw won 2,583 games as the Giants manager, the most in Giants history. While managing the Giants, the team won the National League championship 10 times—in 1904, 1905, 1911, 1912, 1913, 1917, 1921, 1922, 1923 and 1924. They played in the World Series nine times (no World Series was played in 1904){{cite book|title=The Sports Encyclopedia Baseball|author=Neft, D, Cohen, R. & Neft, M.|year=2000|page=[https://archive.org/details/sportsencycloped2000neft/page/24 24]|publisher=St. Martin's Griffin|isbn=0-312-20437-X|url-access=registration|url=https://archive.org/details/sportsencycloped2000neft/page/24}} and won three, in 1905, 1921 and 1922.

McGraw's successor was Hall of Famer Bill Terry, who managed the team from the middle of the 1932 season until 1941. He won 823 games as the Giants' manager, fourth-most in Giants history, and won three National League championships, in 1933, 1936 and 1937, winning the World Series in 1933. Hall of Famers Mel Ott and Leo Durocher managed the team from 1942 through 1955. Durocher was the manager for the Giants' World Series championship in 1954.

The Giants moved from New York to San Francisco in 1958, with Bill Rigney as their manager.{{cite web|title=Giants Timeline|url=http://sanfrancisco.giants.mlb.com/sf/history/timeline7.jsp|archive-url=https://web.archive.org/web/20070805090837/http://sanfrancisco.giants.mlb.com/sf/history/timeline7.jsp|url-status=dead|archive-date=August 5, 2007|publisher=Major League Baseball|access-date=2009-03-15}}{{cite web|title=1958 San Francisco Giants|url=https://www.baseball-reference.com/teams/SFG/1958.shtml|work=Baseball-Reference|publisher=Sports Reference, LLC|access-date=2009-03-15}} They won their first National League championship in San Francisco under Alvin Dark in 1962 but lost the World Series that year. In their first 28 years in San Francisco, they had 14 managers (including two terms by Rigney). Since 1985, the Giants' managerial situation has been more stable. Roger Craig managed the team for more than seven seasons, from the middle of the 1985 season until 1992, including a National League championship in 1989. His successor, Dusty Baker, managed the team for ten years from 1993 through 2002, winning the National League championship in 2002. Baker has the third-highest win total of any Giants manager with 840. Felipe Alou replaced Baker in 2003 and managed the team until 2006. Bruce Bochy managed the team from the 2007 season through 2019, winning World Series championships in 2010, 2012, and 2014, and has the second-most wins among all Giants managers.

Jim Mutrie has the highest winning percentage of any Giants manager, with .605. Heinie Smith has the lowest, with .156, although he managed just 32 games. The lowest winning percentage of any Giants manager who managed at least 100 games is .389, by Jim Davenport in 1985.
