Nechtan is Old Irish, Pictish, Proto-Celtic in Origin.

Nechtan is an early Irish and northern British name, recorded in Old Irish as Nechtán. Its sense is not secure, but many scholars connect it with a Celtic stem necht- or nept- referring to wetness or moisture, the same Indo-European formation often compared with Latin Neptunus, Neptune. The ending -án is familiar in Irish masculine names, though it may have been reinterpreted after the name entered Gaelic tradition.

In Irish myth, Nechtan is linked with Boann and the sacred well whose waters form the Boyne, placing the name within a learned medieval tradition around river origins. Gaelic sources also use Nechtan for several Pictish rulers, including Nechtan mac Der-Ilei in the eighth century, probably reflecting a Pictish cognate rather than simple borrowing. The Latinized Nectan belongs to saints’ cults in Devon and Scotland. Modern use is rare outside Celtic-historical circles.
