Yamachiche (French pronunciation: [jamaʃiʃ] ⓘ) is a municipality in the Mauricie region of the province of Quebec in Canada.

Therefore Yamachiche could have the general meaning of "muddy river", which is a characteristic of this stream.

In 1711, the first chapel was built, dedicated to Sainte Anne by Récollet Siméon Dupont, and the Parish of Sainte-Anne was formed in 1722.

[1][4] In 1725, the Chemin du Roy (French for "King's Highway") was built connecting it with Louiseville and Pointe-du-Lac.

Between 1765 and 1790, Yamachiche grew quickly with new settlers from Acadia (Acadians expelled by the English) and from the United States, particularly Loyalists from Massachusetts.

[1][4] In 1973, the railway station (Canadian Pacific) closed, but in 1975, the new Quebec Autoroute 40 opened, providing access to Yamachiche with 3 interchanges.
