A pony glass may mean one of two types of small glassware:
- A quarter-pint glass of beer: 5 imp fl oz (142 ml), metricated to 140 ml in Australia.
- A small, stemmed glass of about one ounce, similar to a stemmed shot glass. Used for liqueurs or cordials, hence also called a "cordial glass" or "liqueur glass".
- A bar measure that is half of a jigger, used to measure a cordial. A pony traditionally held 1 imp fl oz (28 ml), and is attached to the bottom of a jigger measure, which held 2 imp fl oz (57 ml). In modern times, however, both the size and ratio of the jigger to pony varies widely.

- Notes and Queries, August 8th, 1896, p. 126: “It seems probable the origin is due to the diminutiveness of the glass;”
“The expression ‘a pony of beer’ is often used in South Wales for a small glass containing about the fourth of a pint.”
