Dedemsvaart ("Dedem's Canal") (Dutch Low Saxon: De Voart) is a town in Overijssel, the Netherlands.

The town is located along an old canal, also called Dedemsvaart [nl], which is the source of the village's name.

The canal lost its commercial importance after World War II.

The area around Dedemsvaart, until 2001 part of the municipality of Avereest, was an important centre for industry.

Around two years later, in 1811, the canal had already reached Balkbrug, and the town was established.
