Emil Victor Langlet (26 February 1824 – 10 March 1898) was a Swedish architect.

He was born in Borås. He first made his mark when designing the Norwegian Parliament Building, which was finally completed in 1866. He also drew the city hall and the hospital in Fredrikstad, several villas and Sagatun, the first folk high school in Norway. After 1866 he returned to Sweden, where he oversaw the construction of twelve churches. He still drew the occasional building in Norway, including the theatre in Drammen (1869–1870). He was later given responsibility for the Stockholm Royal Palace.[1]
