England prospects Brad Barritt, Alex Goode and Andy Saull have agreed new three-year contracts with Saracens.
All three have represented England Saxons and played full roles in Saracens' march to the Aviva Premiership final last season.
Centre Barritt is 24 while full-back or fly-half Goode and flanker Saull are 22.
"Each of these youngsters will play a massive role in the future of our club and hopefully in the future of England as well," said Saracens director of rugby Brendan Venter.
"They have committed their futures to us because they believe there's something special happening at Saracens and they want to be part of it."
