Pedro Jaime Martínez (born October 25, 1971) is a Dominican-American former professional baseball starting pitcher, who played in Major League Baseball (MLB) from 1992 to 2009, for five teams—most notably the Boston Red Sox from 1998 to 2004.

Martínez was originally signed by the Dodgers as an amateur free agent in 1988. In his first season in the minors he was assigned to the Great Falls Dodgers where he worked with coach Guy Conti to develop a circle changeup which Conti had learned from Johnny Podres. 

Conti also worked with the young pitcher on his English and helped him assimilate to the United States; Martínez later described Conti as his "white daddy."

As a minor leaguer in the Dodgers farm system, he was a highly touted prospect although some talent evaluators took issue with his "poise" despite his having a "great fastball and circle-changeup."

He made his MLB debut on September 24, 1992, for the Dodgers against the Cincinnati Reds, working two scoreless innings of relief. He made his first start for the Dodgers on September 30, taking the loss while giving up two runs in a 3–1 loss to the Reds.

Although Martínez's brother Ramón, then a star pitcher for the Dodgers, declared that his brother was an even better pitcher than he, the younger Martínez was thought by manager Tommy Lasorda too small to be an effective starting pitcher at the MLB level; Lasorda used Pedro Martínez almost exclusively as a relief pitcher.

Lasorda was not the first to question Martínez's stature and durability; in the minor leagues, the then-135-pound pitcher was threatened with a $500 fine if he was caught running. Martínez turned in a strong 1993 season as the Dodgers' setup man, going 10–5 with a 2.61 ERA and 119 strikeouts, in 65 games; his 107 innings led all NL relievers.

As of 2023, Martínez's record of 219 wins and 100 losses places him tenth-highest in winning percentage in major league history and fifth-highest among pitchers with more than 2,000 career innings pitched.

Martínez ended his career with an earned run average (ERA) of 2.93, among the lowest ever by a pitcher with at least 2,500 innings pitched since 1920. He reached the 3,000 strikeout mark in fewer innings than any pitcher except Randy Johnson and Max Scherzer.

Martínez is the only pitcher other than Scherzer to compile over 3,000 career strikeouts with fewer than 3,000 innings pitched in his career. As of 2023, Martínez's career strikeout rate of 10.04 per nine innings ranks sixth all-time among pitchers with over 1,500 innings.

An eight-time All-Star, Martínez was at his peak from 1997 to 2003, establishing himself as one of the most dominant pitchers in baseball history.

He won three Cy Young Awards (1997, 1999, 2000) and was runner-up twice (1998, 2002), posting a cumulative record of 118–36 (.766) with a 2.20 ERA, while leading his league in ERA five times and in winning percentage and strikeouts three times each. 

In 1999, Martínez was runner-up for the American League (AL) Most Valuable Player Award, after winning the pitching Triple Crown with a 23–4 record, 2.07 ERA, and 313 strikeouts, and the rare feat of winning the Cy Young Award in both the American and National Leagues.

He recorded the second-lowest single-season Fielding Independent Pitching (FIP) in the live ball era (1.39 in 1999), the second-lowest single-season WHIP total in major league history (0.737 in 2000), and the lowest single-season Adjusted ERA+ in major league history (291, also in 2000). .

Although his performance suffered a steep decline in 2004, Martínez ended the season memorably by helping the Red Sox end a long drought in winning their first World Series title in 86 years over the St. Louis Cardinals.
