Humpisschloss Brochenzell, Medieval castle in Meckenbeuren, Germany.

Humpisschloss is a small castle in the Brochenzell district of Meckenbeuren, built in the mid-16th century by the Lords of Humpis on the site of a medieval castle first mentioned in 1277. It was substantially renewed in 1624, when a corner turret and a well were added. Today the building houses a restaurant and a museum about the Humpis trading company.

A castle stood at Brochenzell by 1277, when it was mentioned as "Brobhentel" and sold to Count Hugo von Werdenberg. In 1447 the Lords of Humpis bought the lordship from Count Hugo X. von Montfort and built a small castle on the old site in the mid-16th century. The Weingarten monastery acquired the estate in 1721 and converted the castle into an administrative building in 1748.

The castle reflects the importance of the Humpis family as merchants and landowners in the region. The exhibits show their role in local trade networks and how their business activities shaped the area's economy.

The castle stands in the Brochenzell district of Meckenbeuren, in the Bodenseekreis of Baden-Württemberg. A restaurant and a museum on the Humpis trading company now occupy the building, so visiting depends on their opening hours; check ahead. The former administrative seat is in the village itself, reachable on foot.

The Humpis name survives in a Ravensburg trading company that was among the largest in the Middle Ages, with branches in many European cities; the castle museum is devoted to it. The building itself began as a castle first recorded in 1277 as "Brobhentel", sold that year to Count Hugo von Werdenberg.
