Coir is a natural fibre extracted from the husk of coconut and used in products such as floor mats, doormats, brushes, mattresses, etc. Coir is the fibrous material found between the hard, internal shell and the outer coat of a coconut. Other uses of brown coir (made from ripe coconut) are in upholstery padding, sacking and horticulture. White coir, harvested from unripe coconuts, is used for making finer brushes, string, rope and fishing nets.

Cóir (Irish for "justice") was a social Catholic, conservative Eurosceptic lobby group established to campaign against the Treaty of Lisbon which was approved by referendum in Ireland on 2 October 2009. The group claimed to have had approximately 2,600 campaign volunteers for the 6 months prior to the referendum.
