Schattendorf (Croatian: Šundrof, Hungarian: Somfalva) is a town in the district of Mattersburg in the Austrian state of Burgenland.

This district was a part of the pre-Christian Celtic Kingdom Noricum and was in the vicinity of the settlement Hoehensiedlung Burg on the Burgberg, a 600 meter tall mountain in Austria.

After the end of the World War I, German West Hungary was awarded to Austria after tough negotiations.

In 1921, the town became part of the newly founded federal state Burgenland On 30 January 1927 a small number of armed members of the right-wing Frontkämpfervereinigung were involved in a confrontation with a much larger group of unarmed members of the left-wing Republikanischer Schutzbund.

When they were found not guilty on grounds of self-defence by a jury, the socialists organised a general strike which led to the July Revolt of 1927.
