Johann Gottlieb Christaller (19 November 1827 – 16 December 1895) was a German missionary, clergyman, ethnolinguist, translator and philologist who served with the Basel Mission.
He was devoted to the study of the Twi language in what was then the Gold Coast, now Ghana.
He was instrumental, together with African colleagues, Akan linguists, David Asante, Theophilus Opoku, Jonathan Palmer Bekoe, and Paul Keteku in the translation of the Bible into Twi.
Christaller was also the first editor of the Christian Messenger, the official news publication of the Basel Mission, serving from 1883 to 1895.
He is recognised in some circles as the "founder of scientific linguistic research in West Africa".
