Petitcodiac, sometimes shortened to Petit, is a former village located in Westmorland County, New Brunswick, Canada. The village, named after the Petitcodiac River, held its status until 2023. The river begins in the village at the junction of the North River and Anagance River. The name Petitcodiac is believed to be derived either from a Mi'kmaq word meaning "bends like a bow" or from a Maliseet word meaning "sound of thunder". The village has been known by various names throughout history, including Petcoucoyee (Franquelin, 1686) and Pacoudiac (deCouagne, 1749), with the present spelling being used from the mid 19th century. On 1 January 2023, as part of the 2023 local governance reforms, all or parts of four local service districts were annexed to Petitcodiac to establish a new village named Three Rivers. Despite these changes, the community's name remains in official use.
