Samuel Pond "Sad Sam" Jones (July 26, 1892 – July 6, 1966) was an American professional baseball pitcher who played in Major League Baseball with the Cleveland Indians, Boston Red Sox, New York Yankees, St. Louis Browns, Washington Senators and Chicago White Sox between 1914 and 1935.

In 1918, Jones joined the Red Sox starting rotation, ending with a 16–5 mark, a career-best 2.25 ERA, and a league-best .762 winning percentage.

His most productive season came in 1921, when he posted career-highs in wins (23), strikeouts (98) and innings (298.2), and led the league in shutouts (5).

But his most remembered season may have been 1923 as the ace of the Yankees' staff; he posted a 21–8 record with a 3.63 ERA and led his team to their first World Series title.

After four years of service for the White Sox, Jones retired in 1935 as the oldest active player at the time (42).
