Norma Christine Waterson (born 15 August 1939) is an English musician, best known as one of the original members of The Watersons, a premier English traditional group. Other members of the group included her brother Mike Waterson and sister Lal Waterson, and in later incarnations of the group her husband Martin Carthy.

Waterson was born in Hull, East Riding of Yorkshire and brought up there by her half-Gypsy grandmother. Her eponymously titled solo debut Norma Waterson was produced by John Chelew and released by Hannibal Records in 1996, and was well received in the scene (including a nomination for the prestigious Mercury Music Prize), featuring collaborations with her daughter, Eliza Carthy, Martin Carthy and other members of The Watersons, as well as Danny Thompson (Pentangle), Richard Thompson (Fairport Convention) and Roger Swallow (Albion Country Band).
