Lars Helge Werner (25 July 1935 – 11 January 2013) was a Swedish socialist politician.
Werner was born in Stockholm. He was a member of the Swedish parliament from 1965 to 1994. A construction worker by profession, he was elected vice chairman of the Vänsterpartiet Kommunisterna (VPK) ("the Left Party - Communists") in 1967, and became party chairman in 1975. During his time as party leader, he worked to distance the party from the Soviet Union, a process that had been started by his predecessor as party leader, C.-H. Hermansson. In 1990, VPK changed its name to Vänsterpartiet ("the Left Party"), removing the term "Communists". Werner resigned as party leader in 1993, and was succeeded by Gudrun Schyman.
Werner died from heart problems in 2013, at the age of 77.
