Jake Flannery has signed a contract extension that will see the out-half remain at Ulster until 2026.
The 23-year-old joined the province from Munster last year and has made four appearances.
The Tipperary native also featured on the Emerging Ireland tour to South Africa last October.
"I've really enjoyed this past year with Ulster Rugby," he said.
"I’m delighted to be signing on again for the next three years. I’m excited to progress as an individual and play in a great squad as we continue to compete for silverware."
Meanwhile, backs Angus Curtis and Luke Marshall have also signed new deals with Dan McFarland’s side, who were beaten in the Heineken Champions Cup last-16 by Leinster last weekend and sit in third place in the BKT URC.
Curtis, 25, has signed a two-year deal, while 32-year-old Marshall has extended his stay by another season.
Earlier this week, Ulster announced new deals for Andrew Warwick, Dave McCann and Ben Moxham, Eric O'Sullivan, Greg Jones, Shea O'Brien, John Andrew, Callum Reid and Aaron Sexton.
