Cheddar sauce, cheddar cheese sauce, or cheese sauce is a traditional sauce used in English cooking. The sauce is based upon Béchamel (white) sauce, which is known as one of the 'mother sauces', and cheddar cheese. It could be seen as an English equivalent of the French Mornay sauce{{cite book | last=Holmberg | first=M. | last2=Silverman | first2=E. | title=Modern Sauces | publisher=Chronicle Books | year=2012 | isbn=978-0-8118-7838-8 | url=https://books.google.com/books?id=BPSnLwyGqPgC&pg=PA118 | access-date=January 12, 2017 | page=118}} (itself a variant of Béchamel sauce traditionally mixed with half Gruyère and half Parmesan). The sauce is made by adding an amount of cheddar cheese to white sauce and then spiced using English mustard, Worcestershire sauce and pepper among other ingredients{{Cn|date=June 2025}}

It can be purchased both as a ready to use sauce and as a powder in British supermarkets. In the United States, a mass-produced cheddar sauce is purveyed under the Ragú brand, and is called "double cheddar sauce".{{cite book | last=Joachim | first=D. | title=The Spaghetti Sauce Gourmet: 160 Recipes from Four Kinds of Sauce | publisher=Fair Winds Press | year=2006 | isbn=978-1-61673-400-8 | url=https://books.google.com/books?id=10RRywt8i8wC&pg=PA15 | access-date=January 12, 2017 | page=15}}
