Visby is a Swedish Navy class of corvettes named after the city of Visby and built by Kockums, Karlskrona. The class has received widespread international attention because of its stealth capabilities and network-centric design. The first ship was launched in June 2000.

It is made from carbon fibre, and its angular design reduces its radar signature (or cross-section). Its 57 mm cannon can be retracted to further reduce its radar cross section.

As of 2006, five ships of this class have been built:

HMS Visby 2000
HMS Helsingborg 2003
HMS Härnösand 2004
HMS Nyköping 2005
HMS Karlstad 2006

A Visby class corvette derivative competed in the American Focused Mission Vessel Study, led by Northrop Grumman in partnership with Kockums AB and Howaldtswerke Deutsche Werft AG (HDW). The program was a precursor to the Littoral Combat Ship(LCS) program. It competed with several other concepts including Norway's Skjold class (part of a Raytheon lead group).
