Parkeston /ˈpɑːrkstən/ is a North Sea port village in Essex, England, situated on the south bank of the River Stour about one mile (1.6 km) up-river from Harwich. In 2018 it had an estimated population of 932.

In the 1880s, reclaimed land that had been Ray Island was developed by the Great Eastern Railway Company (GER) as a railway depot for import/export trade with the European mainland. The new port was named Parkeston Quay, after Charles Henry Parkes (1816–1895), Chairman of the GER. The existing railway line was re-routed to pass through the port, although the original railway embankment, through an overgrown area known locally as The Hangings, still exists. Most of the terraced housing in Parkeston was built for railway employees and some of the streets in the village have names that can be theoretically linked to the shipping and general activities of the railway, examples being Tyler Street (paddle steamer The Lady Tyler), Hamilton Street (paddle steamer Claud Hamilton), Adelaide Street (paddle steamer Adelaide) and Princess Street (paddle steamer Princess of Wales).

Claud Hamilton, a former chairman of GER, also gave his name to Hamilton Park, the extensive playing fields between the village and the station/quay area.

Parkeston is known locally as "Spike Island" or "Cinder City". The "Cinder City" name was particularly appropriate given the large areas of marshland or saltings that were reclaimed, frequently using waste material from the railway activities.

There are very few examples of villages established by a railway company to house its workers for an extensive railway and shipping service. This operation also included a locomotive shed and extensive marine workshops to service a fleet of vessels based at the port, which comprised up to a dozen ferries and cargo vessels at its peak.

From early in the 20th century, major passenger ferry services were developed, mainly to the Hook of Holland (with the slogan "Harwich to the Hook of Holland") and later to Esbjerg in Denmark. During both World Wars Parkeston served as an important naval base. Parkeston Quay is now named Harwich International Port and the railway station is named Harwich International. Parkeston is also now faced, across the Stour estuary, by the UK's busiest container port, the Port of Felixstowe.

Other than the port, the area of Parkeston that has seen the largest expansion in recent years is Harwich Gateway Retail Park, a retail district located in what is otherwise known as Iconfield Park, an area of land next to the port on the outskirts of Parkeston. The first shop to be built in the location was Safeway, a supermarket that opened in March 1997, and is currently a Morrisons store. This stood alone for many years, until a flurry of activity in the mid-2000s saw the proper formation of the retail park: a multi-unit development opposite the supermarket, the discount supermarket Lidl off the roundabout between the two, a Premier Inn and Brewers Fayre (opened October 2004 alongside Lidl, and most recently a Home Bargains store, opened in November 2014 on the opposite side of the retail park. There has also been a small housing estate called "The Gateway" built next to Lidl to accommodate the growth of the area.

Most recently, the retail park has also seen the arrival of a McDonald's and a Costa. In 2022 a Greggs opened.

As of February 2015, Focus has been replaced by B & M, and Bon Marché has closed, with no replacement. The pink area marked "Iconfield" on pages four and five denotes the location of Home Bargains.
