The name of the island derives from Old Norse Flatey, meaning a "flat island", and Cuan, a Scottish Gaelic word meaning "ocean" (or bay in Irish and Old Gaelic). The latter probably refers to the Minch, which is known as An Cuan Sgìth ("Ocean of Skye") or Cuan na Hearadh ("Ocean of Harris"). The suffix is also added to distinguish this island from the many others with similar names.
Fladda-chùain is the subject of some legends.
There are the ruins of a chapel here, said to have been founded one "O' Gorgon" in the days of St. Columba, and/or dedicated to him. It is said also that MacDonald of the Isles hid his deeds here prior to the Jacobite rising of 1715.
In 2002 the nuclear submarine HMS Trafalgar grounded on Fladda-chùain whilst travelling at 14.7 knots (27.2 km/h) during a traverse of the Fladda-chùain-Eilean Trodday trough, resulting in some damage to the submarine and three minor injures to the crew. After the grounding the submarine re-surfaced and proceeded to the Faslane base by surface transit. The main cause of the accident was reported as being the use of tracing paper to cover the navigational chart to protect it from being written on, so obscuring vital information. Damage to the hull cost an estimated £5 million to repair.
