The C. Grimaldis Gallery is a contemporary and modern art gallery founded in 1977 by Constantine Grimaldis. As the longest continually operating gallery in Baltimore, it closed its original exhibition space in 2026 and now operates primarily online, focusing on primary and secondary market sales and curated virtual exhibitions. The gallery maintains a consulting office in Baltimore, where it continues to represent a select group of artists and works closely with collectors and institutions. In addition to advisory and gallery activities, C. Grimaldis Gallery participates in art fairs throughout the United States. The gallery specializes in post–World War II American and European art, with a particular emphasis on contemporary sculpture.
