Leeds have made Rotherham flanker Ryan Burrows their fourth new signing for the 2011-12 season.
Burrows, who made more than 100 appearances in four seasons with the Titans, has signed a two-year contract at Headingley.
Leeds assistant coach Mark Luffman said: "Ryan is a very exciting player and someone who comes with a fine pedigree from Rotherham.
"He knows what it takes to compete in the Championship."
He added: "He also has the potential to play at the highest level."
"I had some fantastic times at Rotherham but I felt the time was right for me to move to a new club and test myself," said Burrows.
