Meaning & origin

Dain is an extremely rare given name in the United States. According to U.S. Social Security data, the name was first recorded in 1943 and peaked in popularity in 1978, though it has never been common. In 2025, it ranked 6,143 with a frequency of 1 in 122,005 boys. The name has seen a slight upward trend since 2020, though it remains quite uncommon. Its rarity and simple, one-syllable sound may appeal to parents seeking a distinctive yet straightforward name for their son.

Dain is a rare given name that may derive from the English surname Dain, itself perhaps from the Middle English 'daine' meaning 'dean' or 'valley'. It has also been used as a variant of Dane, referring to someone from Denmark. The name saw some use in the mid-20th century but remains uncommon.
