Kurt Østervig (1912–1986) was a Danish furniture designer.
Trained as a shipbuilder in Odense on the Danish island of Funen, Østervig's attachment to wood rather than steel led to him being employed as a furniture designer in E. Knudsen's Studio, among the greatest of all time. In 1947, Østervig established his own studio, from which he collaborated with several of Scandinavia's largest furniture manufacturers. Particularly fond of working with oak, often combined with leather, he designed many special sets of furniture for ships, hotels, cinemas and nursing homes. His distinctive designs aroused wide international interest, resulting in his work being exhibited in the New York Museum of Modern Art. Among his more notable pieces from the 1950s are an elegant but simply shaped daybed and a free-standing shelf set with a bar.
