The Battle of Älgarås took place at the royal estate of Älgarås in northernmost Västergötland in November 1205 between the House of Sverker and the House of Erik fighting for the Swedish crown. The brothers Jon, Joar, Knut and Erik Knutsson were staying at the estate when the Sverker clan attacked. All the brothers were slain but Erik.
The estate was burnt down completely and abandoned, and it is no longer known exactly where it was located. An oral tradition says that it was "2000 paces from the church of Älgarås in the direction where the sun rises in September".
