Following that season, the New York Yankees acquired Martinez, along with Jeff Nelson and Jim Mecir, for Sterling Hitchcock and Russ Davis.
Before the trade was finalized, Martinez and the Yankees agreed to a five-year, $20.25 million contract extension.
Martinez succeeded Don Mattingly as the Yankees' starting first baseman.

Martinez helped lead the New York Yankees to World Series championships in 1996, 1998, 1999, and 2000.
He also won the Home Run Derby in 1997.
 Martinez hit two memorable home runs as a Yankee in the World Series.
The first came off Mark Langston in Game 1 of the 1998 Series.
The Yankees had tied the game earlier in the inning with a Chuck Knoblauch 3-run home run.
The following three batters got on base, and Martinez came to the plate.
After taking a very close ball 3, he hit a grand slam into the upper deck on a 3-2 count, giving the Yankees a four-run lead.
The second came on October 31, 2001.
With two outs in the 9th inning and the Yankees trailing by two runs, Martinez came to the plate with a runner on.
He hit a home run to right center off Arizona Diamondbacks closer Byung-hyun Kim.
The feat was repeated the following night by Scott Brosius.
However, the Yankees would lose Games 6 and 7 and thus the series.

His best season statistically came in 1997, when he was second in the American League in home runs and RBI (with 44 and 141 respectively), and finished second in AL Most Valuable Player voting.
On May 19, 1998, he was hit in the upper back by Baltimore Orioles pitcher Armando Benítez, which resulted in a huge brawl between the two teams.

In the 2001 World Series, Martinez's Yankees faced off against the Arizona Diamondbacks.
The series went to Game 7, which Arizona won when Luis Gonzalez, Martinez's best friend, hit a game-winning single off Yankee closer Mariano Rivera in the bottom of the 9th inning.
Gonzalez later recalled that when he went back home to check his answering machine, the first message of congratulations was from Martinez.

During most of his time with the Yankees, Martinez resided in Tenafly, New Jersey.
