Chloe Elizabeth Sutton Mackey (born February 3, 1992) is an American competition swimmer who specializes in freestyle and long-distance events.

Chloe's adored "little" brother Colin, who ultimately grew to 6'5" and 285 pounds, played football for the University of Colorado; he currently enjoys a career in finance.

Bypassing her college eligibility, Chloe became a professional swimmer on December 22, 2009 during the annual Elite Pro-AM Meet held in Oklahoma City.

She won the first international medal of her career at the 2006 Pan Pacific Swimming Championships, winning the 10-kilometer open water event.

[14][15] In June 2012, Sutton became the first American to make Olympic swimming teams in both open water and pool events.

At the 2012 Summer Olympics in London, she finished tenth in the preliminary heats of the 400-meter freestyle, and was not among the top eight to advance to the final.
