Nashwaaksis is a neighbourhood and former village in the city of Fredericton, New Brunswick; it is located on the east bank of the Saint John River and at the mouth of the Nashwaaksis Stream, which should not be confused with the larger Nashwaak River nearby. The word Nashwaaksis comes from the Maliseet language, with the "-sis" appendage meaning "little Nashwaak".
The Nashwaaksis area was first used for seasonal farming by the Mi'kmaq and Maliseet peoples. The first European contact was by the French in the late 17th Century, who granted the land to Joseph de Villebon. In 1692, he built a fort (Fort Nashwaak) on the north side of the Saint John River, at the mouth of the Nashwaak River. After de Villebon's death in 1700 and a devastating flood, the fort was abandoned.
Nashwaaksis was settled in the 1760s following the Seven Years' War and developed into a riverfront community opposite what would become the provincial capital at Point Ste-Anne. The community grew with improved transportation links to the city, first with ferry services, then railway and road bridges, culminating in the present Westmorland Street Bridge which includes the perimeter road Route 105 around the neighbourhood.
The community of Nashwaaksis became a neighbourhood of Fredericton following municipal amalgamation in 1973.
