County captain Andrew Gale is among 11 players to have committed their futures to Yorkshire.
The Tykes narrowly missed out on the LV County Championship title on a dramatic final day of the 2010 season and have quickly moved to retain the services of their key men.
Gale, 26, has led from the front by penning a deal that will see him remain at Headingley until the end of the 2013 campaign.
He has been joined in signing up until 2013 by Richard Pyrah, Steve Patterson, England all-rounder Tim Bresnan, Adam Lyth, Jonathan Bairstow and Oliver Hannon-Dalby.
Anthony McGrath and Joe Sayers have penned contract extensions that will see them remaining with the Tykes until the end of the 2012 season.
In addition, youngsters Moin Ashraf and Gurman Randhawa have inked their first professional contracts.
Moin celebrated playing his first two LV County Championship matches by taking his first five wicket haul (5-32) against Kent in the last game of the season, while Gurman was named Yorkshire Academy player of the year for the second year running.
The signings come after Yorkshire also lured Ryan Sidebottom back to the club after he helped Nottinghamshire win this year's County Championship.
"After a very promising season in 2010 we are all aware of the importance of keeping this exciting, young and talented group of players together," said Yorkshire's director of professional cricket Martyn Moxon.
"To have so many players committing their future to the club this early in the winter is excellent news and gives us a tremendous platform on which to build ahead of next season."
