Bellarena (derived from French belle "beautiful" + Latin arena "sand, strand")[1] is a small village and townland in County Londonderry, Northern Ireland.

The land was settled in the mid-17th century by a Northamptonshire gentleman, William Gage, who bought the lease of the estate – then called Ballymargy from the Irish Baile an Mhargaidh[2], meaning "town of the market" – from the Lord Bishop of Derry.

The village is a minor service centre providing retail, community and recreational facilities for the local rural population.

It has had considerable growth in recent years, with new private housing development and improved commercial facilities.

[3] Bellarena has benefited from being close to a range of important tourism facilities including the recreational facilities, Blue Flag beach and caravan parks at Benone, the Magilligan to Greencastle (County Donegal) ferry[4] and the nearby long-established Ulster Gliding Club[5] at Bellarena Airfield.
