Brennun is Irish in Origin.
Brennun is a modern English respelling of Irish Brennan, itself an Anglicized surname from Ó Braonáin ("descendant of Braonán"). Braonán is a diminutive of Old Irish braon, "drop, moisture, tear," which yields readings such as "little drop" or poetically "teardrop." Pronounced BREN-un, Brennun preserves the surname’s cadence while emphasizing a contemporary, distinctive look.
As a given name, Brennan gained favor in North America and the wider Irish diaspora during the late 20th century, alongside other surname-first choices. Brennun appears infrequently in records, offering a rare yet recognizable alternative. Common variants and cognates include Brennan, Brennen, Brennon, Brenan, and Brannon; related but etymologically separate choices are Brendan and Brandon. Usage skews masculine, though the sound and modern spelling occasionally see unisex adoption.
Brennun does not appear in any of the birth registries or name datasets we track. This usually means it's either extremely rare, a regional/traditional name not captured by official statistics, or a brand-new coinage. Use it knowing your child will almost certainly be the only one in the room.
