The Philistine language is the extinct language of the Philistines. Very little is known about the language, of which a handful of words survived as cultural loanwords in Biblical Hebrew, describing specifically Philistine institutions, like the seranim, the "lords" of the Philistine five cities, or the ’argáz receptacle, which occurs in 1 Samuel 6 and nowhere else, or the title padî.

Philistia was a confederation of five main cities or pentapolis in the Southwest Levant, made up of principally Gaza, Ashkelon, Ashdod, Ekron, and Gath, and for a time, Jaffa.
