Innishannon (Inis Eonáin) is a village on the main Cork–Bandon road (N71) in County Cork, Province of Munster, Ireland. Situated on the River Bandon, its small Gaelic Athletic Association pitch had been known to flood in the past, but due to recent works is now one of the finest in division, this pitch was lucky not to be swallowed up by greedy developers during the recent building boom, however the local club Valley Rovers are a very successful club, and have another dual pitch faciltiy in Brinny. It has rapidly grown in recent years, due to its proximity to Cork and has now become a dormitory town for city workers.
The Inishannon bridge which crosses the Bandon river has been present in various incarnations since the 1600s. The original bridge was destroyed in the tidal wave backlash that swept Europe after the earthquake in Lisbon
in 1755. The wave swept up the River Bandon, causing destruction and killing thousands from Kinsale
and up along the river. The River Bandon, originally navigable to Bandon town, for the first English settlers, was permanently lowered to a much lower water level, making further down river Collier's key the closest reachable port.
In 2006 Innishannon had a population of 678.
The parish of Innishannon stretches from the nearby Dromkeen to close to Aherla
