"This Endris Night" (also "Thys Endris Night", "Thys Ender Night" or "The Virgin and Child") is a 15th-century English Christmas carol. It has also appeared under various other spellings. Two versions from the 15th-century survive, one republished in Thomas Wright, Songs and Carols Now First Printed, From a Manuscript of the Fifteenth Century (London: The Percy Society, 1847), and the other in the possession of the Advocates' Library in Edinburgh, Scotland, a legal deposit belonging to the Faculty of Advocates, a role which was assumed by the National Library of Scotland from 1925 onwards. All non-legal collections were given to the National Library.
It has been praised for the unusual delicacy and lyrical flourish for a poem of the period. The opening lyrics, in the Wright edition, are:
Thys endris nyȝth I saw a syȝth, And ever among A mayden song
