Marina Gilardoni (born 4 March 1987 in Goldingen) is a Swiss skeleton racer and former bobsleigh brakewoman.
After starting her sporting career in heptathlon at the club level, Gilardoni began racing bobsleigh in 2007 and earned a place on the Swiss national team.
She won gold medals at the Junior World Championships in 2008 behind driver Fabienne Meyer and in 2010 with Sabina Hafner driving.
After the 2009–10 season, she switched from bobsleigh to skeleton.
In 2018, Gilardoni was selected to represent Switzerland in the Winter Olympics in Pyeongchang after the Dutch Olympic Committee refused one of their two entries and it was reallocated to Switzerland.
