'''Oud-Aa''' is a hamlet in the [[Netherlands|Dutch]] province of [[Utrecht (province)]]. It is a part of the municipality of [[Stichtse Vecht]], and lies about 13&nbsp;km northeast of [[Woerden]].
The hamlet was first mentioned in 1138 as "juxta lacum qui vocatur A" (translation: Next to the lake called A), and refers to the Aa River which is a tributary of the [[Angstel River]]. Oud (old) has been added to distinguish from [[Nieuwer-Ter-Aa]].<ref>{{cite web|url=https://etymologiebank.nl/trefwoord/oudaa |title=Oud-Aa - (geografische naam) |website=Etymologiebank |access-date=27 March 2022 |language=nl}}</ref> The postal authorities have placed it under [[Breukelen]],<ref>{{cite web|url=https://postcodebijadres.nl/3621 |title=Postcode 3621 in Breukelen |website=Postcode bij adres |access-date=27 March 2022 |language=nl}}</ref> and there are no place name signs.
