Twydall is a suburb of Gillingham in Kent in south-east England. In 1998 responsibility for local government was transferred from Kent County Council to the newly created Unitary Authority of Medway, The origin of the name Twydall is thought to mean "Two Parts" or "Double Portion" from the Old English twidǣl, but by 1240 it was written Twydele. Two Palmerston forts were built in the area, Grange Redoubt and Woodlands Redoubt: the design used came to be known as the Twydall Profile.

Modern Twydall is situated between the A2 and the railway line, but previously it stretched down to the Medway estuary to Sharp's Green and Eastcourt Meadows which are now part of the Riverside Country Park and crossed by the Saxon Shore Way. Many of the road names in Twydall are names after villages within Kent. Districts in the surrounding area include Gillingham, Hempstead, and the Lower Rainham and Rainham Mark areas of Rainham. Lower Twydall is a distinct settlement to the north of Twydall.
