Alexander Baumgartner (born in St. Gall, Switzerland, 27 June 1841; died Luxembourg, 5 September 1910) was a poet and writer on the history of literature.

His father was Gallus Jacob Baumgartner, a prominent statesman. At the abbey school of Maria Einsiedeln in Switzerland, where Alexander when fourteen years old began his higher studies, he was influenced by the well-known poet and scholar, Father Gall Morel. The boy's intellectual bent was confirmed at the Jesuit school at Feldkirch, where he spent his last two gymnasial years. After passing an examination he entered the Society of Jesus in 1860. After his studies in 1874 he was assigned to the editorial staff of the periodical Stimmen aus Maria-Laach, which had been founded three years before. He wrote for the journal for thirty-six years, with writings of his appearing in virtually every issue. Owing to the expulsion of the Jesuits from Germany, he repeatedly changed the place of publication of the periodical.

He also took two long journeys. In 1883 he went to Iceland, the Faroe Islands, Scandinavia, and the provinces of the Baltic as far as St. Petersburg, Russia. Three years later he visited Denmark, Sweden, and Norway. Both tours are commemorated in his travel books, Nordische Fahrten (1889 and 1890). He was buried in the cemetery in Luxembourg near his old friend and countryman, the Jesuit Father Joseph Spillman.
