The Smith's Snackfood Company is a British-Australian snack food company owned by American multinational corporation PepsiCo. It is best known for its brand of potato crisps. The company was founded by Frank Smith and Jim Viney in the United Kingdom in 1920 as Smiths Potato Crisps Ltd, originally packaging a twist of salt with its crisps in greaseproof paper bags which were sold around London. The dominant brand in the UK until the 1960s when Edinburgh's Golden Wonder took over with Cheese & Onion, Smith's countered by creating Salt & Vinegar flavour (first tested by their north-east England subsidiary Tudor) which was launched nationally in 1967.

After establishing the product in the UK, Smith set up the company in Australia in 1932. PepsiCo acquired a controlling stake in 1998. Smith's Snackvend Stand is the branch of the company that operates vending machines.
