Siegfried Lehmann (Hebrew: זיגפריד להמן) (4 January 1892—13 June 1958[1]) was an Israeli educator and founder and director of the Ben Shemen Youth Village.

Lehmann was born in Berlin, Germany, in 1892 to an assimilated Jewish family.

In 1927, he immigrated to Mandate Palestine, now Israel, and founded the Ben Shemen Youth Village, a large agricultural boarding school, situated adjacent to the moshav in Ben Shemen.

He directed Ben Shemen Youth Village from 1927 to 1957 and received the 1957 Israel Prize in Education for it.

In 1940, he was imprisoned by the British Mandate authorities because they found arms depots at the village (the "Ben Shemen trial").
