Orla Mølgaard-Nielsen (1907–1993) was a Danish architect and furniture designer. After training at the Aalborg Technical School and at the Art and Crafts School of the Design Museum in Copenhagen, Mølgaard-Nielsen studied furniture design under Kaare Klint at the Royal Danish Academy of Fine Arts. From 1944, his work was mainly carried out in partnership with Peter Hvidt at the Hvidt + Mølgaard studio.
Hvidt + Mølgaard's pioneering sets of furniture included Portex and Ax, based on a laminating technique and produced by furniture maker Fritz Hansen. The chairs were specially designed for export, economising on space and packaging requirements for transportation. They increasingly took on architectural assignments (from 1970 together with Hans Kristensen). Projects covered office buildings and factories, including the De Danske Sukkerfabrikker Building in Copenhagen (1958), as well as collective housing projects in Søllerød, Hillerød and Birkerød (1962–1970), all completed in a light, clear and simple style.
