Clayton Jordan Albertson (born October 11, 1993) is an American long-distance runner, who competes for Brooks Running. He is the world record holder in the 50-kilometer run, with a time of 2:38:43.

Albertson ran collegiately for Arizona State. There he broke the school's indoor 5000m record, had four program top-10 times, and qualified for the 2016 NCAA Championships in the steeplechase.

In April 2019, Albertson ran a 2:17:59.4 marathon indoors at the Armory in New York City, setting the world record for the indoor marathon.

In July 2020, Albertson announced via Instagram that he had received a professional running contract with Brooks.

At the 2021 Boston Marathon, he broke away from the pack and led the race for the first 20 miles before fading to 10th overall. He said later in an interview, "I wasn't running hard; I'm just really good at downhills."

On October 8, 2022, he broke the world record in the 50 km by running 2:38:43 at the Ruth Anderson Memorial Endurance Run in San Francisco.

He is the son of Kent and Cathy Albertson. He has a brother named Michael. In the summer of 2016, he married his Arizona State University teammate, Chelsey.

Albertson is the Head Coach for Clovis Community College Cross Country/Track & Field team. He has also coached at West Ranch High School in Santa Clarita. In his first year, he led both the Men's and Women's teams to State Championships and in his second year, the women's team achieved a third place finish at the Northern Regional Championships.
