Wepre Woods, an ancient woodland in the town, is controlled by Flintshire County Council's Ranger Service and includes Ewloe Castle which dates from the 13th century.

[7] Thomas Morgan stated that this name was a corruption of the ancient Wybre, (Gwybre or Gwybra in Modern Welsh).

The town's English name dates from the late eighteenth century, when a number of new quays were built for the New Cut channel to the sea (construction in 1737).

[9] Other theories given for the origin of the name have included: The earliest recorded settlements date from the time of the Domesday Book,[10] listed as 'Wepre', part of the Hundred of Ati's Cross, Cheshire.

Until the 18th century, the area where Connah's Quay and its neighbours Shotton, Aston and Queensferry now stand was nothing more than fields and a handful of inhabitants.

It was not until the silting of the River Dee ended Chester's port activities that people and commerce began to flood in.

With the success of the Irish Mail trains, the dock was connected by the Wrexham, Mold and Connah's Quay Railway to the nearby town of Buckley, chiefly to transport bricks, clay and pottery products.

The street Leighton Court was built in 1998 on the site of the former station forecourt as well as the former WMCQR line, which had been lifted many years before.

Fishermen would row out across the river in an arc, paying out a long net over the stern of the boat as they went: see seine fishing.

Facilitated with the lifting of the Buckley line, by the 1970s the town had absorbed the nearby hamlets of Golftyn, Kelsterton and Wepre and many housing projects were developed.

As with many small towns, the decline of local commerce has resulted in Connah's Quay overdeveloping its houses at the expense of shops and businesses.

As a result, the town's population has swollen from a few hundred inhabitants to close to twenty thousand over a period of 50 years.

While the town itself does not have many businesses, energy production is a major industry in the area and the town is home to Connah's Quay Power Station, a 1498MW gas fired station on the south side of the Dee, which utilises gas not only from the Dee estuary but also the Douglas Complex located further afield at Talacre.

Crime statistics in 2013 ranked Connah's Quay (central) as the 5th highest rate in Flintshire with neighbouring Shotton (east) placed worst.

[17][18] Connah's Quay Urban District Council built itself a headquarters at 286 High Street in 1929, which was replaced in the 1960s by the Civic Centre on Wepre Drive.

The town is mentioned in the lyrics of the Catatonia song "Imaginary Friend" which is found on the album Paper Scissors Stone.
