Anne Griffith (1734–1821) was a Welsh practitioner of folk medicine who was an early user of foxgloves to treat heart conditions.
She spent all of her adult life at a small cottage, Bryn Canaid, in the area of the parish called Uwchmynydd.
This was before it had been formally "discovered" by the British scientist William Withering.
She also acted as a midwife and among the children was Richard Robert Jones otherwise known as the linguist Dic Aberdaron.
Information is known about her work due to studies of William Jones (Gwilym Daron) who lives in Aberdaron.
