The Irish fullback has penned a new deal to 2023 with the Blades.
"As a group we have built on that success from last season, but we do not want it to stand still. We will continue to do well and finish as high in the table as possible," says Stevens.
Stevens, 29, has played a total of 122 matches for the club, as well as earning 14 caps for the Republic of Ireland.
Blades boss Chris Wilder said: "Enda has become one of the top players in the division, in his position, in our opinion, and he deserves rewarding with a new contract, that's what we're trying to do at the moment.
"His performances have been outstanding for both club and country and he is an important and integral part of our team in and out of possession."
