Ablett, 32, is a seven-time Grand Final winners and holds the record for most appearances in a Grand Final without defeat, and he is now signed up until the end of 2020.
Winger Briscoe, 24, re-joined the Rhinos from Featherstone midway through last season, going on to score five tries in 10 appearances.
Director of Rugby, Kevin Sinfield, said: “We are pleased to be able to offer all three players new contracts. Jamie and Carl are outstanding clubmen who epitomise the culture and ethos we cherish here at Leeds.
“However, more importantly both players are still able to do a valuable job for the team on the field as well and have earned their new deals.
“There has never been any question over Luke’s ability however his early career was frustrated by injuries. He is a great example to any young player who suffers a set back.
“He has continued to work hard, listen to his coaches and give his very best every time he steps onto the field and deserves this contract with the Rhinos.”
