Honister Pass is a mountain pass in the English Lake District. It is located on the B5289 road, linking Seatoller, in the valley of Borrowdale, to Gatesgarth at the southern end of Buttermere. The pass reaches an altitude of 1,167 feet (356 m), making it one of the highest in the region, and also one of the steepest, with gradients of up to 1-in-4 (25%). The saddle at the watershed is known as Honister Hause, using the Cumbrian word hause for such a feature. Flowing through the pass from the summit to Buttermere is Gatesgarthdale Beck.

Honister Pass is one of three passes that link the tourist area around Keswick, including Derwent Water and Borrowdale, with the valley of the River Cocker, including the lakes of Buttermere, Crummock Water and Loweswater. From north to south these passes are Whinlatter Pass, Newlands Pass and Honister Pass.

Honister Slate Mine and Honister Hause Youth Hostel are located at the summit of the pass.

Honister Pass holds the UK 24-hour rainfall record; in the 24 hours to 6 pm on 5 December 2015, 341.4 mm of rain fell there.
