Krabi (Thai: กระบี่) is a town (thesaban mueang) on the west coast of southern Thailand at the mouth of the Krabi River where it empties in Phang Nga Bay. As of 2005 the town had a population of 24,986. The town is the capital of Krabi Province and Krabi District. Tourism is an important industry.

At the start of the Rattanakosin or Bangkok period in the late eighteenth century, when the capital was finally settled at Bangkok, an elephant kraal was established in Krabi by order of Chao Phraya Nakorn (Noi), the governor of Nakhon Si Thammarat, which was by then a part of the Thai Kingdom. He sent his vizier, the Phra Palad, to oversee this task, which was to ensure a regular supply of elephants for the larger town. So many followers emigrated in the steps of the Phra Palad that soon Krabi had a large community in three different boroughs: Pakasai, Khlong Pon, and Pak Lao. In 1872, King Chulalongkorn graciously elevated these to town status, called Krabi, a word that preserves in its meaning the monkey symbolism of the old standard. The town's first governor was Luang Thep Sena, though it continued a while as a dependency of Nakhon Si Thammarat. This was changed in 1875, when Krabi was raised to a fourth-level town in the old system of Thai government. Administrators then reported directly to the central government in Bangkok, and Krabi's history as a entity separate from other provinces, had begun.

Facing the Andaman sea, like Phuket, Krabi is subject to a 6-month rainy season between May and November, often with sustained heavy rains for days at a time during the monsoons.
