Sweethope Loughs are two freshwater lakes in the southern part of Northumberland, England, lying between the A68 and A696 roads roughly 18 miles west of Morpeth.

The larger lough covers around 140 acres and the smaller about 12 acres; a crossing connects the two. Both are tree-lined and set among rolling hills, with Great Wanney Crag and Little Wanney Crag visible to the northwest.

Together they form the headwaters of the Wansbeck River. The site has a long-standing reputation as one of the region's best trout fly fisheries, with rainbow trout available to anglers of all skill levels.

Boats are available on the water, and coaching is offered for those new to the sport. Holiday cottages sit on the southern bank of the Little Lough, and a small caravan site occupies the north bank.

Easy walking routes of roughly 3–4 miles encircle the loughs, passing through wooded sections and open countryside on gentle gradients suitable for most fitness levels.
