The British farthing (¼d) coin, from "fourthing", was a unit of currency of one quarter of a penny, or 1/960 of a pound sterling. It was minted in bronze, and replaced the earlier copper farthings. It was used during the reign of six monarchs: Victoria, Edward VII, George V, Edward VIII, George VI and Elizabeth II, ceasing to be legal tender in 1960. It featured two different designs on its reverse during its 100 years in circulation: from 1860 until 1936, the image of Britannia; and from 1937 onwards, the image of a wren. Like all British coinage, it bore the portrait of the monarch on the obverse.

The original reverse of the coin, designed by Leonard Charles Wyon, is a seated Britannia, holding a trident, with the word FARTHING above. Issues before 1895 also feature a lighthouse to Britannia's left and a ship to her right. Various minor adjustments to the level of the sea depicted around Britannia, and the angle of her trident were also made over the years. Some issues feature toothed edges, while others feature beading.
