The Athinganoi or Athingani, plural of Athinganos, are a ninth-century sect of Monarchians located in Phrygia, founded by Theodotus the banker.

The etymology of the word is not certain, but a common determination is a derivation in Greek for "(the) untouchables" derived from a privative alpha prefix and the verb thingano (θιγγάνω, to touch).

It is uncertain whether the sect survived beyond the ninth century.

They are probably scattered across Anatolia and the Balkans following the destruction of the Paulician capital Tephrike in the 870s.
