Russell Nathan Jeanson Coltrane Martin, Jr. (born February 15, 1983, in East York, Ontario) is a Canadian Major League Baseball catcher for the Los Angeles Dodgers.

Martin's career as a Major League Baseball player began in 2006. During that year, he hit .282. Convinced they had a find, the Dodgers made him their starting catcher in 2007, where he has been ever since. During Martin's first three years in the majors, the Dodgers made it to the post-season twice.

Martin was born in East York, Ontario (in the east end of Toronto). He grew up in Chelsea, Quebec, Canada and lived in Paris, France from the age of 8-10. Martin has an African Canadian father, Russell Martin Sr., and a white, French Canadian mother, singer and actress, Suzanne Jeanson. His parents separated when he was only two years old. "I don't really remember when my parents separated, and it's probably better that way because I know kids these days go through some tough times," says Martin. His father used to play saxophone in Montreal subway stations to help pay for his baseball training. Along with playing baseball in the Montreal neighborhood of Notre-Dame-de-Grâce, Martin played hockey for N.D.G Minor Hockey, where glimpses of his future all-star athleticism could be seen. He graduated from Polyvalente Édouard-Montpetit High School, which was the same high school attended by former teammate Éric Gagné. After graduating from high school, Martin took a junior college scholarship at Chipola College in Marianna, Florida.
