Nectan is Celtic in Origin.

Nectan is a Celtic masculine name rooted in Old Irish Nechtan/Nechtain (Scottish Gaelic Neachdainn), from the adjective necht “pure, clean, clear; holy,” likely from Proto-Celtic *nektos. In early Irish lore Nechtan is the guardian of a sacred spring from which the River Boyne flows, so the name carries strong associations of purity, clarity, and hallowed waters.

The name was borne by several early Pictish rulers - most prominently Nechtan mac Der Ilei (early 8th century) - and occurs across Gaelic and Brittonic hagiography, notably Saint Nectan of Hartland, venerated in Devon and Cornwall (Latinized Nectanus). Medieval usage in Ireland and Scotland fed into surnames such as Ó Neachtain (anglicized Naughton) and Mac Neachtain/MacNaughton. Today Nectan/Nechtan is rare as a given name but familiar in historical and ecclesiastical contexts. Variant forms include Nechtan, Neachtan, Neachtain, Neachdainn, and Nectanus; Anglicized spellings usually simplify to Nectan or Nechtan.
