Nino Mier Gallery is a contemporary art gallery founded in 2015 in West Hollywood by Austrian-born dealer Nino Mier, who worked as a private art advisor before opening his first space with a roster centered on then-largely-unknown painters from Germany's Rhineland. The gallery expanded steadily, adding a project space in Cologne in 2018 and further locations in Los Angeles, Brussels, and Marfa, Texas, before opening in New York, first in Soho and then in Tribeca in 2023. It now represents roughly fifty living artists and estates, with a program centered on painting, sculpture, and photography, and presents rotating solo and group exhibitions across its New York and Brussels spaces.
