Sasu is Finnish in Origin.

Sasu is a modern Finnish given name, chiefly masculine, used both independently and as a familiar short form. In Finland it most often derives from the Slavic pet name Sasha for Alexander (Finnish Aleksanteri), adapted to local phonology as Sasu; in some families it is also a nickname for Sampsa, the Kalevala-era name of the mythic sower. The name gained broader domestic use in the late twentieth century and remains recognizable through contemporary Finnish bearers.

Meaning follows its source: from Alexander/Aléxandros (“to defend” + “man”), Sasu carries the sense of defender or protector. When taken from Sampsa, it evokes associations with sowing, growth, and renewal in Finnish folklore rather than a fixed etymology. Variants and cognates include Sasha, Sacha, Sascha, Saša/Sašo (South Slavic), and Finnish forms such as Aleksanteri, Aleksi, and Sampsa. Outside Finland, Sasu is rare but easy to pronounce and stylistically brisk.
