Erró (Iceland, 1932) is an Icelandic Pop artist known for his work in collage. He reassembles imagery from a variety of popular sources including advertisements, comics, and posters, earning him comparisons to earlier Pop artists such as Roy Lichtenstein, Andy Warhol, and James Rosenquist.

He was born Guðmundur Guðmundsson in 1932 in Ólafsvík, Iceland and studied engraving, fresco, and painting at the Academy of Oslo. He began exhibiting his work in the mid-1950s, and in 1989 he donated his archives to the City of Reykjavik, establishing the Erró Collections within the Reykjavik Art Museum. In 2000, the Icelandic Parliament awarded him the Honorary Artists Stipend, and the following year, a museum dedicated to his work opened in Reykjavik. A major retrospective of 50 years’ worth of his collages was held at the Centre Pompidou in Paris in 2010.
