Bubikon Castle or Bubikon Commandery (German: Ritterhaus Bubikon) is a castle in the municipality of Bubikon of the Swiss Canton of Zürich. The former Commandery, a medieval monastery of the Knights Hospitaller, is a Swiss heritage site of national significance.

Assumably in compensation of claims related to the Alt-Rapperswil lands and rights, a change of goods occurred between the Counts of Toggenburg and Counts of Rapperswil probably in the early 1190s. To end the disputes about the legacy, the Knights Hospitaller abbey and commandry was given by Diethelm V von Toggenburg and Vogt Rudolf von Rapperswil between 1191 and 1198 AD. Although in concurrency to the neighbouring Rüti Abbey, the commandery's lands and goods grew with donations by local noble families during the 13th and 14th centuries – at the height of their power, the commandry owned land all over the present canton of Zürich.

The commandry's inhabitants was granted Burgrecht by the neighbouring town of Rapperswil, later by the city of Zürich. During the Reformation in Zürich and the riots in the Herrschaft Grüningen against the feudal owners of the lands cultivated by the farmers and their families, Johannes Stumpf, the commander of the commandry at the time, supported its secularization and those of the neighbouring Rüti Abbey in spring 1525. The lands partially became the property of the city of Zürich when the convent was secularized in 1528 (convent) respectively 1798 (commandry).
