Philippine folk literature refers to the traditional oral literature of the Filipino people. Thus, the scope of the field covers the ancient folk literature of the Philippines' various ethnic groups, as well as various pieces of folklore that have evolved since the Philippines became a single ethno-political unit.
While the difference between Philippine folk literature and Philippine mythology is a fine one, this article distinguishes folk literature as the source from which Philippine mythology derives
While the oral, and thus changeable, aspect of folk literature is an important defining characteristic, much of this oral tradition has been written into a print format. To point out that folklore in a written form can still be considered folklore, Utely points out that folklore "may appear in print, but must not freeze into print." It should be pointed out that all the examples of folk literature cited in this article are taken from print, rather than oral sources.
Eugenio classifies Philippine Folk Literature into three major groups: Folk narratives, folk speech, and folk songs.
Folk narratives can either be in prose - the alamat (folklore), the legend, and the kuwentong bayan (folktale) - or in verse, as in the case of the folk narrative.
Folk speech includes the bugtong (riddle) and the salawikain (proverbs).
Folk songs can be sub-classified into those that tell a story (folk ballads), which are rare in Philippine folk literature, and those that do not, which form the bulk of the Philippines' rich heritage of folk songs.
Since it comes from a Southeast Asian nation, Philippine folk literature can be counted as a representative of Southeast Asian folklore. This is not a simple categorization, however, for two important reasons.
First, Southeast Asia as a distinct cultural region was not recognized until the political environment after the Second World War.
Second, even as the idea of a Southeast Asia was being conceived, the inclusion of the Philippines in the region was consistently in debate because of its very different cultural makeup.
Setting those two objections aside, Philippine Folk Literature would be considered a subset of the folklore of peninsular Southeast Asia, which includes the folklore of Malaysia, Indonesia, and Brunei. This would be distinct from the folk literature of continental Southeast Asia, which includes Vietnam, Thailand, Myanmar, Cambodia, and others. The distinction roots from the geographical influence on the cultures arising from these countries.
