Baltic mythology is the body of mythology of the Baltic people stemming from Baltic paganism and continuing after Christianization and into Baltic folklore. Baltic mythology ultimately stems from Proto-Indo-European mythology. The Baltic region was one of the last regions of Europe to be Christianized, a process that occurred from the 15th century and into at least a century after. While no native texts survive detailing the mythology of the Baltic peoples during the pagan period, knowledge of the mythology may be gained from Russian and German chronicles, later folklore, by way of etymology, and comparative mythology.
