Darri is of Icelandic origin, meaning 'gift'. It is often used as a short form for names like Darri Þór. The name gained prominence due to its use by the first president of Iceland after independence in 1944, Þór Guðmundsson, whose middle name was Darri.
"Darri saw a notable increase in popularity between 1959 and 1964, with a peak of seven births recorded in 1964. After a decline, it remained relatively stable until the recent resurgence in 2021, totaling to 34 births."
