Debdale Wharf is a canal access point and marina on the Grand Union Canal (Leicester Line), situated roughly a mile and a half north of Foxton and about two miles east of Saddington Tunnel, in a rural Leicestershire setting.

It has historical significance as the point where the Leicester Line canal first opened in April 1797, when construction paused before continuing south toward Foxton and Market Harborough.

Today the site operates as Debdale Wharf Marina, offering a full range of boating services including moorings, boat repairs, fuel, chandlery, pump-out, and hull blacking.

It is noted in waterways guides as providing all standard marina and boatyard facilities for boats travelling the Leicester Line.
