The Rangers will add Dan Muse to the coaching staff as an assistant to Peter Laviolette, The Post has learned.

Muse, who will turn 41 next month, coached Team USA to the gold medal in the IIHF Under-18 World Championships in Switzerland this April in his third year as a head coach with the USNDP.

Prior to that, Muse spent three years as an assistant coach with the Predators, with Laviolette as head coach.

He previously served as head coach for the USHL Chicago Steel for two years after six years as an assistant or associate coach for Yale University.

It is not known what specific role Muse — whose teams also won championships in Chicago and at Yale — will be assigned with the Rangers.

The Blueshirts are also expected to name Michael Peca as an assistant to the staff.

It is unclear whether Kevin McCarthy, Laviolette’s longtime assistant through tours in Philadelphia, Nashville and Washington, will be part of it here.

Goaltending coach Benoit Allaire and skills coach Mark Ciaccio are holdovers from Gerard Gallant’s regime.
