Dolphin fountain is a decorative water feature device with a dolphin theme. Usually composed of sculptures of one or more dolphins, these sculptures may be leaping out of the water, swimming, jumping, or other postures. The design of the dolphin fountain is dedicated to showcasing the elegance, agility, and vitality of dolphins.

Dolphin fountains are commonly found in water areas such as swimming pools, water parks, and ocean theme parks, and may also be used for land landscapes such as gardens and courtyards.
