The name Sainte-Hélène-de-Mancebourg recalls the memory of two women, Helena, mother of Constantine I, and Jeanne Mance.

Saint Helena's greatest claim to fame is the discovery of the True Cross during a trip to the Holy Places in 326, according to a widespread legendary tradition.

Jeanne Mance co-founded the city of Montreal.

The ‘bourg’ element underlines the presence of an inhabited core on the territory.
