Johann Heinrich Hübschmann (1 July 1848 – 20 January 1908) was a German philologist.

He studied Oriental philology at Jena, Tübingen, Leipzig, and Munich; in 1876 he became professor of Iranian languages at Leipzig, and in 1877 professor of comparative philology at Strasbourg.

Hübschmann died on 20 January 1908 in Freiburg im Breisgau.

[1] Hübschmann was the first to show in 1875 that the Armenian language was not a branch of the Iranian languages (earlier assumed so because of the immense amount of Iranian influence on Armenian throughout its history) but an entirely separate Indo-European branch in its own right.

[2] He used the comparative method to separate the Iranian loanwords, which make up the majority of the Armenian loanwords, from an older layer of native Armenian words.
