Squash (sometimes called cordial) is a concentrated, often fruit-based, syrup to which water is added. It is also the name of the resulting drink.

It is common in the United Kingdom and Ireland, especially among toddlers and young children. Typically, squash is created by mixing one part syrup with four or five parts water (depending on concentration of the syrup and personal taste), directly into a glass or mug or into a jug. The most common flavours are: orange; apple and blackcurrant; lemon and lime. Other flavours include peach, strawberry, kiwi fruit Common manufacturers of squash include Robinsons, GlaxoSmithKline (under the Ribena brand) and supermarkets.

In the West Indies the name "squash" is used to describe a lime juice drink, similar to lemonade.
