Nechtain is Gaelic, Irish in Origin.

Nechtain is a masculine name of Goidelic and Pictish origin, from Old Irish Nechtán/Nechtain, built on the Celtic stem necht- meaning “pure, clean, holy.” In early literature it is tied to the figure Nechtan, guardian of a tabooed well whose waters gave rise to the River Boyne when his wife Boand defied its boundary - a myth underscoring the name’s association with sacred purity and water.

The name flourished in early medieval northern Britain and Ireland, especially among the Picts: rulers such as Nechtan mac Der-Ilei (8th century) are recorded for reforming the church and consolidating royal power. It appears in saints’ traditions too, notably Saint Nectan of Hartland, which spread the English form Nectan. Variants and cognates include Nechtan, Nechtán, Nectan, Neachtain (Modern Irish), Neachdainn (Scottish Gaelic), and Brittonic Neithon; the surname Ó Neachtáin (anglicized Naughton) preserves the same root. Today Nechtain is rare yet richly historical.
