A highball glass (often shortened to just highball or even hi-ball) is a type of drinking vessel. It is distinguished by having vertical sides, and being relatively tall and narrow. A standard highball holds 200 mL (7 oz) of liquid. Highball glasses are typically used for serving light spirits, as opposed to dark spirits which are usually served in tumblers.

A "highball" was an early mixed drink featuring rye and ginger ale over ice. This is the original recipe for a highball which then became the generic name for mixed drinks. "Cocktail" has since become the catch-all phrase, however, a true cocktail is two or more liquors with no mixers or ice. A "martini glass" is really a cocktail glass. The highball glass differs from a collins glass by being shorter and unfrosted.

Examples of cocktails commonly served in highball glasses are the Tequila Sunrise and the Long Island Iced Tea. Drinkware
