The steelpan (also known as a pan or steel drum) is a musical instrument originating in Trinidad and Tobago. Steelpan musicians are called pannists.

In 1992, the steelpan was declared Trinidad and Tobago’s national instrument by Prime Minister Patrick Manning. This helped turn the steelpan into a source of national pride and cultural identity, recognized both locally and internationally.

In 2023, the United Nations General Assembly declared 11 August as World Steelpan Day. The following year, the Parliament of Trinidad and Tobago officially recognised the steelpan as the country's national instrument.

The modern pan is a chromatically pitched percussion instrument made from 200-litre industrial drums.

Drum refers to the steel drum containers from which the pans are made; the steel drum is more correctly called a steel pan or pan as it falls into the idiophone family of instruments, and so is not a drum (which is a membranophone). Some steelpans are made to play in the Pythagorean musical cycle of fourths and fifths.

A pan is played using a pair of straight sticks tipped with rubber; the size and type of rubber tip varies according to the class of pan being played. Some musicians use four pansticks, holding two in each hand. This grew out of Trinidad and Tobago's early 20th-century Carnival percussion groups known as tamboo bamboo.

The pan is the national instrument of Trinidad and Tobago and appears on the country's current coat of arms.

Steelpans developed in the early to mid 1900s, but with roots going back much earlier, including the talking drums of West African cultures which were used for ceremonies and communicating messages at a distance.
