Gilles Senn (born 1 March 1996) is a Swiss professional ice hockey goaltender for HC Ambrì-Piotta of the National League (NL).

[1] While growing up in Switzerland, he had limited exposure to the National Hockey League but as he grew older, he began to idolize NHL goaltenders David Aebischer and Martin Gerber.

[1] He worked alongside his backup Joren van Pottelberghe to help lead HC Davos to the semi-finals, before eventually losing 5–3.

[14] In the next game, on 21 December, Senn made his first NHL start, making 35 saves and allowing three goals in a 5–1 loss to the Columbus Blue Jackets.

[15] After two seasons playing within the Devils' organization, Senn as a restricted free agent, opted to return to Switzerland and sign a three-year contract with original club, HC Davos, on 27 May 2021.

[18] During the 2017–18 season, Senn was selected as the third goaltender for Team Switzerland during the 2018 IIHF World Championship, behind Genoni and Reto Berra.
