Cristfried Ganander was a Finnish compiler of folk culture, a priest and an 18th-century lexicographer. Ganander's greatest achievement was the compilation of the first fully extensive Finnish-language dictionary which was, however, unpublished. He was also a collector of folk culture well before Elias Lönnrot. His most well-known published work is Mythologia Fennica in 1789, a reference book of folk religion. He also published some poetry and worked as a teacher.
