Tyresö Royal Crowns is a Swedish sports club established in 1990 with American football as its only section.

The club currently plays at Tyresövallen in the municipality of Tyresö in the southeastern part of the Stockholm metropolitan area.

A one time national champion (2001), the team is currently a contender in Superserien; the first tier of the Swedish football pyramid.

The under 19 is the oldest existing youth program and enjoyed particular success in the seasons 2009–2011 with three back-to-back national championships.

Since Tyresö and Carlstad both entered Superserien in 1998, the two teams have had many fierce battles with the latter most frequently coming out on top.
