Andrija Mohorovičić (IPA ['ʌndɹɪja mɔhɔ'ɹɔvɪtʃɪtʃ]) (January 23, 1857 – December 18, 1936) was a notable Croatian meteorologist and seismologist. He is best known as the eponym for the Mohorovičić discontinuity.

Early years
His career began with a teaching post in the Zagreb gymnasium (1879 -1880) and then secondary school in Osijek. In 1882, he began to teach at the Royal Nautical School in Bakar, near Rijeka, where he remained for nine years. Works initiated or done there were crucial for the beginning of Mohorovičić's scientific work. From 1893, when he became a corresponding member, to 1917-18 he taught subjects in the fields of geophysics and astronomy at the Faculty of Philosophy, University of Zagreb. In 1898 he became a full member of what was then the Croatian Academy of Sciences and Arts in Zagreb where he was private docent, and in 1910 he became titular associate university professor.
