Mattice-Val Côté is an incorporated township in Cochrane District in Northeastern Ontario, Canada.

Mattice was founded in the 1910s, fueled by the arrival of the Canadian Transcontinental Railway and free land given away by the government.

[4] Major Gregor Lenox Mattice was educated at the Royal Military College, Kingston, Ontario, Canada, and graduated as a civil engineer.

The history of Mattice-Val-Côté and its residents is detailed in the two volume book Si Missinaïbi m'était conté.

Mattice is home to a historical First Nations cemetery, located two kilometers south of town.

The first "journées médiévales" (Medieval Days) took place in the summer of 2006, inspired by a similar activity in a small Quebec town.

This festival features the naming of a king and queen for the day, a competition to become a knight, a lot of family activities, a variety of different expositions and a meal without utensils.

Residents and visitors enjoy outdoor sports such as hunting, fishing, snowmobiling, camping, swimming and canoeing.
