Mark Sloan is a fictional surgeon on the ABC television series Grey's Anatomy. The character is portrayed by actor Eric Dane. Mark was born to an upper-class but emotionally distant family in New York City.

At a young age, he befriended Derek Shepherd and became like a second son to the Shepherd family, although he would eventually sleep with at least one of the Shepherd sisters, Nancy. Their friendship lasted throughout childhood and into their adult years, and Mark was Derek's best man at his wedding to Addison Montgomery. Mark attended medical school at Columbia University College of Physicians and Surgeons, completed his residency in otolaryngology, a fellowship in plastic surgery, and quickly became one of the most highly-regarded plastic surgeons on the East Coast with a thriving private practice.

As Derek and Addison's marriage became strained, Mark and Addison grew closer, and eventually Mark slept with Addison, only for Derek to catch them in the act. After Derek declared his marriage to Addison and friendship with Mark over and left town, Mark and Addison lived together for two months. During this time, Addison became pregnant with Mark's baby.

He was initially excited about the pregnancy, but Addison had an abortion amidst rumors of Mark's infidelity, and soon left Mark to follow Derek to Seattle Grace.
