Lynwood Thomas "Schoolboy" Rowe (January 11, 1910 – January 8, 1961) was an American right-handed pitcher in Major League Baseball, primarily for the Detroit Tigers (1932–42) and Philadelphia Phillies (1943, 1946–49). He was a three-time All-Star (1935, 1936, and 1947) and a member of three Tigers' World Series teams (1934, 1935 and 1940).

Rowe was born in Waco, Texas, in 1910. He was brought up in El Dorado, Arkansas, and attended El Dorado High School. Growing to 6 ft 4 in (1.93 m), Rowe was an all-around athlete, receiving all-state football honors as a quarterback, competing in over 100 professional boxing matches, and playing for the Brown Paper mill basketball team that advanced to the semifinals of the national A.A.U. tournament. He also competed in tennis and golf.

There were varying published accounts of how Rowe got the nickname "Schoolboy".

In 1932, Rowe began his professional baseball career with the Beaumont Exporters, the Texas League affiliate of the Detroit Tigers. He appeared in 31 games, 29 as a starter, compiling a 19-7 record in the regular season with a 2.30 earned run average (ERA). He also hit ten home runs and compiled a .290 batting average. The 1932 Exporters won 100 games and the Texas League championship, with Rowe pitching and future Detroit Tigers teammate Hank Greenberg leading the team in batting.

Rowe was promoted to the Tigers' big-league roster in 1933 after only one season in the minor leagues. He appeared in his first major league game on April 15, pitching a complete game shutout against the Chicago White Sox. His rookie season was cut short in July by a shoulder injury sustained while throwing to first base after fielding a bunt. He appeared in 19 games, 15 as a starter, compiling a 7-4 record with 75 strikeouts and a 3.58 ERA.

In the spring of 1934, Rowe's arm remained unwell. The team's new player-manager Mickey Cochrane threatened to send Rowe back to minors if the arm did not improve. He remained with the Tigers but performed poorly early in the season, giving up nine earned runs in 5-1/3 innings in the month of April for an ERA of 15.19. He began to hit his stride in late May and registered an American League record 16 consecutive wins from June 15 to August 25. He finished the regular season with a 24–8 record.

In the 1934 World Series against the St. Louis Cardinals' Gashouse Gang, Rowe was 1–1 in two starts with a 2.95 ERA. In Game 2, Rowe pitched a 12-inning complete game, allowing two earned runs and retiring 22 consecutive batters. In Game 6, Rowe pitched another complete game, allowing four runs, but Paul "Daffy" Dean held the Tigers to only three. Schoolboy finished fourth in the American League's 1934 Most Valuable Player voting behind teammates Mickey Cochrane, who won, and Charlie Gehringer.

With his southern charm and eccentricities, Schoolboy Rowe became a fan favorite in Detroit. He was known as a superstitious player who carried good-luck charms, including "a magical US Eagle ten-dollar coin" as well as "enchanted copper pieces from Belgium and The Netherlands, a fortunate black penny from Canada and a chipped but still powerful jade elephant from the Orient." He also avoided stepping on the chalk line while walking to and from the mound, always picked up his glove with his right hand and dropped it with his left hand, and even talked to the ball.
