Uncle Joe's Mint Balls are mints produced by William Santus & Co. Ltd. in Wigan, Greater Manchester, England since 1898.

The ingredients of Uncle Joe's Mint Balls are pure cane sugar, oil of peppermint and cream of tartar and are described on the tin as "suitable for vegans".

As of 2011, 160,000 mint balls are made per day, which is around 35 million per year.
