Burton "Gus" Guster is a fictional character on the USA Network television comedy Psych played by American actor Dulé Hill. He functions as the straight man for Shawn Spencer's antics, and provides sobering advice, steady support, and friendship. Over the course of the show, Gus evolves from nothing more than a conventional, uptight pharmaceutical representative to a strong support system through all Shawn Spencer's crazy antics. He frequently tries to pass himself off as "fearless" although in reality the opposite is true, and often cries, sometimes due to "sympathy" and other times when Shawn is insensitive to his feelings. It is believed that Gus was named after a relative of Steve Franks, the technical producer of the show, Burton Franks.

Gus has been Shawn Spencer's best friend since childhood, and co-owns the detective agency "Psych" with him, after Shawn was able to forge Gus' name on the lease. Gus tends to be straight-laced and more cautious, although he has been friends with Shawn for long enough that he understands that Shawn cannot be stopped once his mind has been made up. Shawn will often make up silly aliases for Gus while working a case. Gus has stated that he is not used to being introduced by his real name.

Gus is often shown to be academically advanced. As a child, he applied for and was accepted into the Meitner School for gifted students; however, his parents turned down the placement, later telling Gus that it was too far to drive. In middle school, he was involved in spelling bees until 1989, when he lost a competition by accepting covert advice from Shawn on the spelling of "." He continues to follow the American Spelling Bee meticulously, and tapes the yearly championship. He was also voted most likely to succeed in high school and is upset that he has not done more in life. However, after helping Shawn solve a murder, he realizes that he leads a very productive life and he's happy with what he has done. Guster also attended Pomona College (class of 1998), something he shows off in multiple episodes.

Gus's parents, Bill and Winnie Guster, are shown to be overly protective of their son and still regard him as a child who needs looking after. They long disapproved of his friendship with Shawn, whom they regarded as a bad influence. After Shawn and Gus solve a murder for which Bill and Winnie had been wrongfully arrested, they mellow towards Shawn and admit that perhaps they do not need to baby Gus so much. (However, immediately after Gus leaves, they offer Shawn cash with a stern order to look after their son.) A brother has been referenced in Gus' blog on the official USA Network website, but received no mention in the show. In the deleted scenes for "Gus' Dad May Have Killed an Old Guy" on the Season 2 DVD, Gus's mom mentions a brother who lives in Connecticut. In the episode "Christmas Joy", Gus' family comes to town for the holidays, including Gus' sister Joy, who shares a mutual attraction with Shawn.
