Knightstown (Irish: Baile an Ridire, also An Chois),[2] alternatively called Knight's Town, is a village and the largest settlement on Valentia Island, County Kerry, in Ireland.

[1] In 1830 Maurice FitzGerald, the 18th Knight of Kerry, commissioned Scottish engineer Alexander Nimmo to draw up plans for a new village.

Knightstown is also the location of the car ferry connection between Valentia Island and Reenard Point on the mainland.

The area served as a base of operations for the laying of the first successful Transatlantic telegraph cable to Heart's Content, completed in 1866.

[5] Knightstown participates in the annual "Tidy Towns" competition where it is regularly recognized for the quality and cleanliness of its environment.
