Slack Roman Fort was a castellum near Outlane, to the west of Huddersfield in West Yorkshire, England. Its site is a scheduled monument. The ruins of the fort which lay alongside the Pennine section of the Roman road from Deva Victrix (Chester) to Eboracum (York) are no longer visible. The fort may have been the Cambodunum mentioned as a station on this route in the Antonine Itinerary.

Archaeological digs indicate the fort was constructed of turf and wood to defend the Roman road in the time of Agricola in AD 79. Outside the fort walls was a stone bath-house which was extended around AD 104 and AD 120. A vicus or small settlement of wooden huts grew outside the fort.

In December 2016, a retired professor from Bangor University, Peter Field, hypothesised that the fort's site was a potential location for the mythical Camelot.

The site of the fort is on gently sloping ground sheltered by a hill rising to 1,200 feet (366 m) above sea level about 4 miles (6 km) from Huddersfield. Observation posts on the surrounding hills commanded views towards Blackstone Edge, Standedge, Huddersfield and the Stainland Valley in the Halifax direction.
