Internationales Keramikmuseum, Ceramic museum in Weiden in der Oberpfalz, Germany.

The Internationales Keramikmuseum occupies the Waldsassener Kasten, a grain store built in the mid-18th century by Baroque architect Philipp Muttone for Waldsassen Abbey. Its roughly 1,000 m² of exhibition space holds German and European porcelain and ceramics from the Rococo period to the 20th century, alongside pieces from Egypt, Asia and other regions, shown in a permanent display reworked in 2025.

Founded in 1990 as a branch museum of the Neue Sammlung in Munich, the museum is housed in the Waldsassener Kasten, a grain store built in the mid-18th century by Baroque architect Philipp Muttone for Waldsassen Abbey. Its core holdings come from the porcelain collection of Dr. Wilhelm Seltmann, donated by his widow, and in 2025 the permanent exhibition was completely reinstalled.

The core of the collection is the Chinese porcelain donated by Dr. Wilhelm Seltmann, a Weiden entrepreneur, in 1994, with pieces from the Qing Dynasty and a focus on the 19th century. Temporary exhibitions on regional themes and the current ceramics scene are curated by the Keramikmuseum Weiden and its friends' association.
