Nathan Mardis Rolison (born March 27, 1977) is an American former professional baseball first baseman.

Rolison played in 2000 with the Florida Marlins of Major League Baseball (MLB).

Rolison attended Petal High School in Mississippi where he carried a 4.0 grade point average and was named the state's high school baseball player of the year.

His only Major League hit, a single, came off of Wayne Gomes in the penultimate game of the season.

That fall, while working out with the Southern Miss Golden Eagles baseball team, Rolison broke three bones in his wrist, an injury which required surgery and which Rolison later called "the beginning of the end" of his career.
