Cliftonville is a coastal area of Margate in the Thanet district of Kent, England. It includes the Palm Bay estate, built in the 1930s with wide avenues and detached and semi-detached houses with driveways, garages and gardens.

The estate covers the eastern part of Cliftonville and was fields when first built. It extends east beyond Northumberland Avenue and has been developed in phases. An earlier phase covered the northern ends of Leicester and Gloucester Avenues and the whole of Clarence and Magnolia Avenues; the later phase extending eastwards of Princess Margaret Avenue is a Wimpy-style housing estate with small houses largely identical in appearance and of less substantial build quality than the original 1930s estate.

The eastward expansion of Cliftonville has included much of the former parish of Northdown including Northdown Park and House.

West Cliftonville was originally developed as an upmarket alternative to Margate and had many small private hotels and guest houses. Many of these have now been converted into Social Housing flats for the Roma community mainly coming from countries including: Czech Republic, Bulgaria and Slovakia. The seafront area once included a large Butlins complex.

The shopping area of Cliftonville is called Northdown Road and includes a number of main banks and building societies, larger corporate concerns including Costa and Tesco, a number of family run specialist shops including an award-winning art gallery, a post office, several pubs and bars, many unique and upmarket coffee shops and cafes, three churches and a number of estate and letting agents as well as an award-winning media company all along its two-mile length.

The Walpole Bay Tidal Pool is a tidal lido pool in the village. The pool was opened in 1937 and is a Grade II listed structure. The pool covers over four acres and its dimensions are 450 ft long, 300 ft wide at the seaward end and 550 ft long at the landward end. It cost circa £7,000. It was designed by Margate Borough Engineer A E Borg.

The Pool covers around 4 acres and is believed to be the largest tidal pool in the UK. During high tide the walls of the pool are totally submerged by the sea. As the tide recedes, water drains out through drainage points around the edge of pool. There are freshwater springs within the walls of the pool which feed into the water.

The pool is popular with the local community and is used regularly throughout the year, even during the winter months. Aside from the nearby carpark there are currently no additional facilities, such as showers or toilets for users of the pool. The pool is never staffed with a lifeguard.
