Hannu is a Finnish masculine given name derived from Johannes, ultimately from Hebrew Yochanan meaning “Yahweh is gracious” or “God is gracious.” It likely entered Finnish through Scandinavian forms such as Hans and Hannes, with the Finnish -u ending shaping the familiar, compact Hannu. The name carries the enduring Christian sense of divine favor.

Recorded in Finland since early modern parish registers and widely adopted in the 20th century, Hannu peaked in mid-century use and today feels traditional yet friendly. Close Finnish variants and cognates include Juhani, Juho, Juha, Jukka, Janne, and Hannes; related international forms span Johannes, Johan, Hans, John, Ian, Sean, Jean, Juan, Ivan, and Giovanni. Less common spellings like Hanno or Hanu occur in other languages but are considered distinct. Finnish tends not to shorten Hannu further, while feminine counterparts include Johanna and Hanna.
