Aodh (/eɪ/; Old Irish: Áed) is an Irish and Scottish Gaelic male given name, originally meaning "fire". Feminine forms of the name include Aodhnait and Aodhamair. It appears in even more variants as a surname. As a surname, the root or a variant may be prefixed by O, Ó, or Ui (meaning "from" or "descendant of") or Mac or Mc (meaning "son of").

The name was originally related to an Irish god of the underworld. The masculine given name Hugh is a common anglicization, although the names are not etymologically linked (see Hughes (surname), Hughes (given name)).

Pet forms of the name formed with the diminutive -án include Aodhán and Ádhán (Old Irish Aedán), names which are sometimes anglicized as Aidan, Aiden, and Edan. A double diminutive is Aodhagán and its modern form Aogán.Maodhóg (Old Irish Máedóc), anglicized Mogue, and the Welsh form are formed from the affectionate prefix mo- and the separate diminutive -og.

It was also used in Roman Britain as a native form of the Latin name Dominus.
