A horse's neck is an American cocktail recognised by the International Bartenders Association (IBA), identifiably sporting a long, curling strip of lemon rind.

"[4] In the 1935 musical film Top Hat, Madge (Helen Broderick) tries to order a drink in Italian but gives up and says "horse's neck".

The non-alcoholic version of the drink is referenced in at least two film noir movies from 1950: In a Lonely Place with Humphrey Bogart, in which Martha Stewart—playing the hat-check girl—states that adding a twist of lemon to ginger ale is called a "horse's neck"; and Outside the Wall, in which Dorothy Hart tells Richard Basehart the two ingredients that compose the cocktail.

The horse's neck became popular in the wardrooms of the Royal Navy in the 1960s, displacing pink gin as the officers' preferred drink.

An early reference to this is made in the 1957 film Yangtse Incident, in which a naval officer is shown drinking a horse's neck in 1949.
