Pickett's Lock (No 15) is a lock on the River Lee Navigation in the London Borough of Enfield, England and is located near Edmonton, London.

Picketts feld (1669) located nearby is also named from this family, who take their surname from one Picot de Marisco ('of the marsh') recorded locally in the 13th century.

[3] The lock is situated on the navigation between the William Girling Reservoir to the east, Deephams Sewage Treatment Works to the west and close to the Lee Valley Leisure Complex golf course.

Angling is allowed on the River Lee Navigation upstream and downstream of the lock.
