Eduard Ahrens (3 April 1803, Tallinn – 19 February 1863, Kuusalu) was a Baltic German Estonian language linguist and clergyman. Ahrens studied at Tallinn University of Theology from 1811 to 1819, and, from 1820 to 1823, at the Faculty of Theology of the University of Tartu. After graduating from university, he could not hold a pastor's office because he was too young (the pastors were to be at least 25 years old), so in 1824 he went to Pikavere manor, where he worked for about 8 years. In 1831, Ahrens revised the pro ministerio exam at the Estonian Consistory. In 1832, he went to study in Germany and also visited France. On returning to Estonia, he again returned to home-schooling at Vana-Vigala (with the Sievers family). Ahrens held sermons in the Vigala church in Estonian.
