Trae Young scored 23 points, including a go-ahead three-point play, and the Hawks beat Utah 117-114 on Thursday night in State Farm Arena to end the Jazz's five-game winning streak.
Young also had 11 assists.
Six other players scored in double figures for the Hawks (25-48).
Former Hawks standout Kyle Korver scored six for Utah (42-30). Korver was honored with a video tribute and received an ovation during a first-period timeout.
Donovan Mitchell led the Jazz with 34 points.
It was a costly loss. Utah entered the game fifth in the Western Conference but only a half-game ahead of a pack of three teams tied for sixth.
The Jazz led 110-109 before Young's basket and free throw with 1:47 gave the Hawks the lead.
The Hawks stretched the lead to four points when an officials' review confirmed a goaltending call against Rudy Gobert on Dewayne Dedmon's shot.
A slam by Gobert, who had 12 points and 11 rebounds, cut Atlanta's lead to 114-112. Dedmon made two free throws. Following a layup by Mitchell, Dedmon made only one of two free throws with 6.2 seconds remaining to give Utah, trailing 117-114, a chance.
Vince Carter fouled former Korver on what was initially ruled a three-shot foul. A review determined Korver would only shoot two free throws. Korver missed both free throws, the second one intentionally, and Mitchell missed a last-second 3-pointer from the corner.
Dedmon had 18 points for the Hawks. Kevin Huerter had 14 points.
Huerter has been overshadowed by fellow rookie Young but also has become a starter with a role in the team's long-term future. "I think the beauty is he's a modern day perimeter player," coach Lloyd Pierce said. Huerter has five games with at least five 3s. Only Young, with six such games, has more among the league's rookies this season.
Former Georgia Tech and South Atlanta High School star Derrick Favors had 15 points and 15 rebounds for Utah.
The Hawks host Philadelphia on Saturday night.
