Verenahof (aka. Büttenharter Hof or Verenahöfe) was a German exclave in Switzerland, administratively part of the German town of Wiechs am Randen (now part of the town of Tengen). Geographically, it was separated from Wiechs am Randen by a 200-300 metre broad strip of Swiss territory.
On 4 October 1967 the territory, consisting of just three houses and fewer than a dozen people, became part of Switzerland in exchange for a similar area of land transferred to West Germany. It now belongs to the Swiss municipality of Büttenhardt.
