A tiki mug is a large ceramic cocktail drinking vessel that originated in tiki bars and tropical-themed restaurants. The term "tiki mug" is a blanket term for the sculptural drinkware even though they vary in size and most do not contain handles. They typically depict Polynesian, mock-Polynesian, tropical, nautical, or retro themes, and as the term is used generically do not always emulate a tiki. When used to serve drinks they are frequently garnished with fruit or decorative drink umbrellas and swizzle sticks.

A tiki bar is a themed drinking establishment that serves elaborate cocktails, especially rum-based mixed drinks such as the Mai Tai and Zombie cocktails. Tiki bars are aesthetically defined by their tiki culture décor which is based upon a romanticized conception of tropical cultures, most commonly Polynesian. Some bars also incorporate general nautical themes or retro elements from the early atomic age.
