The Rotterdamsche Kunstkring (RKK) was an association in the Dutch city of Rotterdam, for and by artists and art lovers.
Its members included visual artists, architects, writers, recitalists, photographers, musicians and designers.
The Kunstkring settled in Hotel du Passage on Korte Hoogstraat and moved to 35 Witte de Withstraat in 1899.
During the reconstruction, entrepreneur and art lover Ludo Pieters became closely involved with the Kunstkring.
First as a board member (1953) and from 1955 as chairman, he remained this until the association was dissolved in 1969.
