Blyth Spartans Association Football Club is an association football club based in Blyth, Northumberland. They are currently members of the National League North, the sixth tier of English football, and play at Croft Park. They were founded in September 1899 by Fred Stoker, who was the club's first secretary before forming a practice as a distinguished physician in London's Harley Street. He thought it appropriate to name the team after the Greek Spartan army in the hope that the players would give their all as they went into 'battle' on the field of play. The club is most notable for its 1977–78 FA Cup campaign, in which they went all the way to the fifth round, eventually losing to Wrexham in a replay at St James' Park.

Blyth () is a town and civil parish in southeast Northumberland, England. It lies on the coast, to the south of the River Blyth and is approximately 13 miles (21 km) northeast of Newcastle upon Tyne. It had a population of 37,339 in the 2011 Census.The port of Blyth dates from the 12th century, but the development of the modern town only began in the first quarter of the 18th century. The main industries which helped the town prosper were coal mining and shipbuilding, with the salt trade, fishing, and the railways also playing an important role. These industries have largely vanished, but the port still thrives, receiving paper and pulp from Scandinavia for the newspaper industries of England and Scotland.The town was seriously affected when its principal industries went into decline, and it has undergone much regeneration since the early 1990s. The Keel Row Shopping Centre, opened in 1991, brought major high street retailers to Blyth, and helped to revitalise the town centre. The market place has recently been re-developed, with the aim of attracting further investment to the town. The Quayside has also seen much redevelopment and has been transformed into a peaceful open space, the centrepiece of which is a sculpture commemorating the industry that once thrived there. On the opposite side of the river are the nine wind turbines of the Blyth Harbour Wind Farm, which were constructed along the East Pier in 1992. They were joined in 2000 by Blyth Offshore Wind Farm, which consisted of two turbines situated 1 kilometre (0.62 mi) out to sea. These were the first two offshore wind turbines in the UK. These wind turbines were all decommissioned, with the final two being removed in 2019. A new windfarm further off the coast, composed of five turbines, was commissioned in 2017. Blyth is also home to the non-League football club Blyth Spartans, famed for their 1978 "giant-killing" feats in the FA Cup.

Blyth Offshore Wind Farm was a small coastal wind farm located 0.5 miles (0.80 km) off the coast of Blyth, Northumberland, England.

Blyth Community Hospital is a health facility in Thoroton Street, Blyth, Northumberland, England. It is managed by Northumbria Healthcare NHS Foundation Trust.

The River Blyth flows eastwards through southern Northumberland into the North Sea at the town of Blyth. It flows through Plessey Woods Country Park. The River Pont is a tributary. The Blyth is 27 miles (44 km) long and the Pont is 17 miles (28 km).The tidal limit of the river is at Bebside. The estuary widens from this point eastwards and with the addition of a burn that enters on the northern side (Sleek Burn), it covers an area of 415 acres (168 hectares).Ecologists have suggested that a dam on the river at Humford Country Park in Bedlington could be removed to allow for fish migration. The local community have expressed a desire to keep the dam as it is a local beauty spot; they have suggested that a fish passage be built alongside instead.

The North Blyth Biomass Project was a proposed biomass-fired power station planned to be located at North Blyth, Northumberland on the north bank of the River Blyth near its tidal estuary. When commissioned it would have had a generating capacity of 100 megawatts, enough electricity to provide for 170,000 homes.Renewable Energy Systems, the station's developer, was granted government consent on 24 July 2013 to build the £250m project. Although the Secretary of State granted a Development Consent Order as a nationally significant infrastructure project, the project was cancelled on 6 March 2014.
