Selianitika (Greek: Σελιανίτικα) is a coastal village in northern Achaea, Peloponnese, Greece.

The villages Selianitika and Longos (adjacent to the northwest) share a fine gravel beach on the Gulf of Corinth which is approximately 1.5 km long.

According to historian A. Fotopoulos, the descent of inhabitants of Seliana from the mountains to the coastal region of "Kryovrysi" near Aigio (where the village of Selianitika lies today) started to happen during the Ottoman period.

The French historian, explorer and diplomat François Pouqueville, who travelled through the area in 1816 does not mention Selianitika but mentions the small neighbouring village of Longos[7] as the only being inhabited after he crossed the river of Phoenix (tholopotamos): "Une humble chapelle et le hameau de Longos sont les seuls lieux habités qu'on ait en vue du côté des montagnes".

In 1874 the researcher and chronicler Archduke Ludwig Salvator of Austria did a research trip by boat in the Gulf of Corinth and he wrote a detailed book with his observations for the landscape and the populated places of north Peloponnese.
