The coat of arms of the Kingdom of Sweden (Swedish: Sveriges riksvapen) has a lesser and a greater version.

The usage of the coats of arms is regulated by Swedish Law, Act 1970:498, which states (in unofficial translation) that "in commercial activities, the coats of arms, the flag or other official insignia of Sweden may not be used in a trademark or other insignias for products or services without proper authorisation. This includes any mark or text referring to the Swedish State which this can give the commercial mark a sign of official endorsement. This includes municipal coats of arms which are registered."

Any representation consisting of three crowns ordered two above one are considered to be the lesser coat of arms, and its usage is therefore restricted by law 1970:498.
