The Väddö Canal (Swedish: Väddö kanal) is an artificial canal first dug in the 16th century to provide a sheltered passage between the Bagghusfjärden [sv] to the south and the Väddöviken [sv] to the north.

The canal separates the island of Väddö from the mainland, and passes through the village of Älmsta at its northern end, and the lake of Storfjärden towards its middle.

[1][2] The canal is routed along, or close to, what was originally a natural waterway, but this ceased to be navigable in the Middle Ages.

By the 18th century, the waterway had again ceased to be navigable, and the current canal was dug by the Swedish Army between 1820 and 1840, with traffic using it from 1835 onwards.
