The Verlengde Hoogeveensche Vaart is a historic canal in the province of Drenthe, in the northeastern Netherlands. It stretches approximately 32.5 kilometres from the eastern edge of Hoogeveen toward Klazienaveen and beyond, eventually connecting to the German waterway network via the Süd-Nord-Kanal near Ter Apel. The canal was originally developed following a concession granted in 1850 to extend the Hoogeveensche Vaart into the peat bogs of Noord- and Zuidbarge. The eastern section, beyond Erica, is also known as the Van Echtenskanaal, as it was constructed by the N.V. Nieuw-Echtens Veen Compagnie. The canal retains its function as a navigable waterway, though on the Zijtak branch, use is now limited to recreational craft.

The canal is managed with locally operated locks and bridges along its length. Paddlers and boaters should be aware that the Noordscheschutsluis marks the point where lock capacity decreases, and from there onward, convoying at a maximum speed of 6 km/h is standard practice. Along the Verlengde Hoogeveensche Vaart alone, there are two locks and 21 bridges, many of which are operated by a single bridge keeper managing several structures in combination, which can result in waiting times. Bridges and locks are operated locally rather than remotely, in contrast to the Hoogeveensche Vaart to the west, where remote operation from Hoogeveen is used.

The canal passes through the flat peat landscape of Drenthe, offering a distinctly low-lying, open character typical of this part of the Netherlands. The route connects to a broader network that includes the Hoogeveensche Vaart to the west and continues toward the Veenpark and Haren on the Ems to the east, making it part of a longer through-route for paddlers and boaters traveling between the Dutch interior and Germany. The Holsloot Bridge is one of the notable crossing points along the canal, located in the Coevorden area of Drenthe. The surrounding region includes access to towns such as Emmen and the broader Drenthe countryside, which can be combined with visits to natural areas in the province.
