The Tikbalang (/ˈtikbaˌlaŋ/) (also Tigbalang, Tigbalan, Tikbalan, Tigbolan, or Werehorse) is a creature of Philippine folklore said to lurk in the mountains and rainforests of the Philippines. It is a tall, bony humanoid (half-human and half-horse) creature with the head and hooves of a horse and disproportionately long limbs, to the point that its knees reach above its head when it squats down. In some versions, it is a transformation of an aborted fetus sent to earth from limbo.

As horses weren't native to the Philippines in the pre-Spanish era, the earliest written records about the tikbalang did not specify horse or animal morphology.

Documents from Spanish friars such as Juan de Plasencia's Customs of the Tagalogs (1589) describe the tikbalang as ghosts and spirits of the forests, associated with the terms multo and bibit.

Entries in early Spanish-Tagalog dictionaries defined tigbalang as "fantasma de montes" (phantoms of the mountains/wilds), linking them strongly as nature spirits.

An offensive expression "tigbalang ca mandin!(You are a wild beast!)" was used by early Tagalogs to signify one as uncouth and uncivilized.

There were also ghosts, which they called vibit; and phantoms, which they called 'Tigbalaang'.

The tigbalang is another object of which they stand in great awe. It is described as a phantom, which assumes a variety of uncouth and monstrous shapes, and interposes its authority, to prevent their performing the duties, prescribed by our religion.
