Joseph Thomas Hesketh (born February 15, 1959) is a former pitcher in Major League Baseball who played from 1984 through 1994 for the Montreal Expos (1984–90), Atlanta Braves (1990) and Boston Red Sox (1990–94).

He also had 10 complete games for the Buffalo Bulls and pitched one of the greatest wins in school history – a 4–0 shutout against powerful St. John's team and future major league star Frank Viola.

[1] After that, he earned the 1980 ECAC New York-New Jersey District Player of the Year honors, as his six shutouts for the Bulls remain a school record.

[2] In 1985 he was 10–5 with a 3.29 ERA in 25 starts, allowing just 125 hits in a career-high 155+1⁄3 innings into late August, but a home plate collision broke his leg and his season was over.

He ended with a 12–4 mark in 39 games for Boston, including 17 starts and a career second-best 153+1⁄3 innings, as his .750 won-loss % topped American League pitchers.
