Goalies Marc-Andre Fleury (26-10-0, 1.98 goals-against average, .928 save percentage) and Robin Lehner (13-4-2, 2.29 GAA, .913 save percentage) combined for seven shutouts and helped the Golden Knights allow 124 goals, an NHL-low 2.21 per game.
"For me, hands down, the best goalie tandem in the League," Vegas coach Peter DeBoer said. "I'm sure they would say this is also a team defense trophy, and I think they got some good help from our commitment to defending. Those two were outstanding every night with us."
The New York Islanders were second, allowing 128 goals (2.29 per game).
It's the first time Vegas goalies have won the Jennings Trophy. Fleury won for the first time; Lehner won for the second time (2018-19 with Islanders).
The Golden Knights (40-14-2) allowed two regulation goals or fewer in 37 of 56 games.
