Abernethy is Scottish in Origin.

Abernethy is a Scottish toponymic name taken from the villages of Abernethy in Perth and in Strathspey. Its elements come from the Pictish/Brittonic aber, “confluence, river mouth,” plus the river name Nethy, yielding the sense “mouth of the Nethy” or “where the Nethy meets another water.” The place was an early Pictish religious center, later marked by an 11th‑century round tower, which helped cement the surname in medieval records.

As a family name it appears in 12th–13th‑century charters with the de Abernethy lords; over time it spread throughout Scotland and, by migration, to Ireland and North America. As a given name, Abernethy is a rare modern transferred surname with a polished, gender‑neutral feel. Common variants include Abernathy (especially in the United States), Abernethie, and Abernethi; occasional short forms are Neth or Nethy. The name signals Scottish heritage and a quietly geographic meaning.
