Hall was again named to the NHL All-Star Game in the 2017–18 season. However, due to a hand injury, he was replaced by teammate Brian Boyle. On February 15, 2018, in a win over the Carolina Hurricanes, Hall set a Devils franchise record with a 16-game point streak. His point streak came to an end at 26 games on March 8 in a 3–2 loss to the Winnipeg Jets; Hall recorded two shots on goal in the game. His 26-game point streak was the longest in the NHL since Patrick Kane's 26-point streak in the 2015–16 season. Hall finished the regular season as the Devils' top scorer with a career-high 93 points (39 goals and 54 assists) as he led the Devils to their first Stanley Cup playoff appearance since 2012. It was also the first time Hall ever played in the playoffs. Hall again led the Devils in the playoffs as their top scorer with six points (two goals and four assists) as the team was eliminated in the first round by the Tampa Bay Lightning, four games to one. On April 26, Hall was nominated for the Ted Lindsay Award as the NHL's most outstanding player. The following day, on April 27, Hall was also declared a finalist for the Hart Memorial Trophy as the NHL's most valuable player. Hall won the latter, becoming the first player in Devils history to win the trophy.
