Lokren (IPA: /ˈlɒkɹən/; full name The Kingdom and Empire of Greater Lokren) is an imperial kingdom in southern Epiros, controlling an extensive empire along the southern and southeastern coasts of the continent.

The modern Lokrenians (IPA: /ləˈkɹiːniənz/) are the descendants of invaders from Anatios, who crossed the Thalas Sea many generations ago to conquer the peoples of south-eastern Epiros and settle themselves in their lands. Lokren's capital city, Mevron, still stands on the coast in the place where those foreign warriors first came ashore.

Unlike most native peoples of Epiros, the Lokrenians are generally quite pale-skinned.

The current ruler of Lokren is King Arryn II.

The Lokrenians speak their own language, which is a rare hybrid of the language of their ancestral homeland, Pallas, and the local dialects spoken by the native peoples they subjugated many centuries ago. They have their own script, which is derived from the one used in Pallas. Lokrenian script is also used to write the Ardryn language.
