Liplje (pronounced [ˈliːpljɛ], German: Liple[2]) is a small settlement north of Planina in the Municipality of Postojna in the Inner Carniola region of Slovenia.

It includes the hamlet of Podgora north-northwest of the village core.

There are some hayfields and tilled land in the karst field itself that are subject to occasional flooding.

[4] The name Liplje is derived from a plural demonym, *Lipľane 'residents of Lipa', itself derived from the common noun lipa 'linden', referring to the local vegetation.

Places named after the linden tree are common in Slovenia, with other examples including Lipa, Lipe, Lipje, Lipica, and Lipce.
