Belinelli barely kept his feet behind the arc when he launched the shot that produced the last of his 22 points and allowed the Bulls to snap a two-game skid.
The winning 3-pointer was one of just four made by the Bulls in 17 attempts. Chicago won despite shooting only 37 percent from the field.
Al Jefferson, who had missed Utah's previous three games with a sprained ankle, returned to score 23 points. The Jazz have dropped three in a row.
