Heinrich Wenzel (7 June 1855 in Mainz – 16 June 1893 in London) was a German Indologist and Tibetologist.
He studied at the universities of Jena, Leipzig and Tübingen, receiving his doctorate at the latter institution with a thesis on the instrumental case involving the Rigveda (1879).
While here, he focused his attention on the then little-known Tibetan language and literature.
From 1881 he spent the next two years in Herrnhut, where he studied Tibetology with Moravian missionary Heinrich August Jäschke.
In 1883 Wenzel published the second edition of Jäschke's "Tibetan grammar".In 1886, he obtained his habilitation at Leipzig with a translation of Nagarjuna's "Suh?llekha".
Later on, he returned to England, initially residing in Oxford, eventually settling in London.
Among his writings were translations of works by Russian scholars.
He reportedly was fluent in a dozen different languages.
