Thorvald Steen (born 9 January 1954) is a Norwegian writer and government scholar. He made his literary debut in 1983, and has subsequently published a wide range of novels, plays, collections of poems, books of short stories, children's books and essays. He has distinguished himself as one of Norway's leading internationally oriented writers. His Norwegian breakthrough came in 1992 with a cycle of poems, Ilden (The Fire) and shortly afterward he achieved international recognition with his creative historical novels Don Carlos (1993), Giovanni (1995), Constantinople (1999), The Little Horse (2002), Camel Clouds (2004) and Lionheart (2010). In 2006 Steen wrote the coming-of-age novel The Weight of Snow Crystals, which was followed in 2008 with the freestanding sequel The Longest Leap.
