Oatfield was a chocolate and confectionery manufacturer located in Letterkenny, County Donegal, Ireland.

By 1960, Oatfield decided to stop marketing packed sweets made by Cadbury's, Rowntree, Urney's Chocolates, Bassetts Licorice Allsorts, Jacobs Biscuits, William and Wood, Ritchies Mints and Milroy Confectionery and focus entirely on selling Oatfield sweets.

At the peak of the company's popularity, the sweets were exported worldwide to countries including the United States, Canada, Hong Kong, Australia, Kuwait, Greece and France.

[1][2] In 2007, Zed Candy—an Irish confectionery company famous for its Chewing Gum—bought the brand from Donegal Creameries.

[3] Up until closure, the factory employed approximately 15 people and up to 65 tonnes of sugar and chocolate confectionery were produced each week.

[5] Since then, the Oatfield brand and all its products continue to be manufactured by Valeo Foods and are still sold across Ireland.
