Gianni Petrus Cornelis Romme (born 12 February 1973)[1] is a Dutch marathoner and a former long track speed skater.

He won two gold medals at the 1998 Winter Olympics in Nagano and was the World all-round champion in 2000 and 2003.

Four years later, at the 2002 Winter Olympics, he captured the silver medal in the 10000 metre event, beaten only by compatriot Jochem Uytdehaage.

International speed skaters Anni Friesinger, Ralf van der Rijst and Risto Rosendahl decided to join his team.

Romme himself wanted to continue his career, but announced at the opening day of the 2007 KNSB Dutch Single Distance Championships that he would no longer participate in long track speed skating, only in marathon speed skating.
