Jean Escatefer dit Cousin (before 1425 – after 1474) was a French or Flemish singer and composer of the Burgundian School and a member of the royal chapel from about 1461.
Until at least 1474, Cousin served as a singer and priest of the French king, and by 1473 he had reached third place in the hierarchy of the orchestra.
It is unclear when his employment was ended due to loss of the court orchestra bills for the period after 1474.
Cousin was recorded as taking part in the Tours city election assemblies in 1463-1464.
Missa Nigra sum mentioned in 1473 by Johannes Tinctoris seems to be lost.
