The club began playing in the Northern League in 1931–32 as Evenwood Town, reaching the first round of the FA Cup in the 1956–57 season.

During that season, manager Graeme Clarke resigned after losing 5–1 to Gateshead[6] on 25 March 2005, followed soon by Secretary Thomas Metcalfe for supposed health reasons.

Headed by Alan Murray the fans rallied round and formed an independent supporters group, initially with the aim of running the club themselves.

[7][8] Both groups submitted their bids with the local council, but after a meeting held at the Penny Gill pub in Spennymoor, it was agreed to stand down and let Alan Murray's plan go ahead.

In the first four home games under the new name, one of those including The F.A Cup preliminary round, the club attracted over 1300 people[10] to The Brewery Field.

In January 2006, Houlahan left his post as manager to become Director of Football and Justin Perry was appointed Player-Manager, finishing the season in a respectable 8th position.

They narrowly missed out on a Durham Challenge Cup final appearance against Sunderland, losing the semi-final to a 120th-minute winner 1–0 at Gateshead.

In the 2008–09 season, the club chairman resigned,[19] but Spennymoor battled against the odds and finished 4th in the league on goal difference below Newcastle Benfield, Consett and Whitley Bay.

[19] The 2009–10 season was a huge success, with the arrival of former Aston Villa player Bradley Groves as Club Chairman,[19] with former England, Newcastle and West Ham United Striker Paul Kitson as president.

Despite winning the league in three consecutive seasons (2009–10, 2010–11, 2011–12), the club did not apply for promotion as they wanted to be financially stable before they took the next step up.

[21] Gav helped Whitley Bay towards 3 consecutive FA Vase victories and also spent a year at Blyth Spartans before joining the Moors.

In the 2013–14 season, Spennymoor Town started off retaining the JR Cleator Cup,[24] as the league champions Darlington declined the invitation to compete.

[26] The club had applied for promotion into the pyramid during the 2013–14 season and played their first competitive game outside of the Northern League away to Padiham on 16 August 2014, winning 2–0.

In the first match, Spennymoor were winning 2–0 by the 90th minute, but Telford scored two goals in injury time[28] to secure the replay.

[32] Spennymoor finished their first season in the NPL Division One North in 5th place on 77 points and but lost 3–2 against Darlington 1883 in the play-off semi-final.

[34] Spennymoor had therefore reached their highest position in the footballing pyramid of any team from the town and took their place in the National League North for the 2017–18 Season.

[36] In December 2020, Jason Ainsley stepped down as Spennymoor manager by mutual consent after 14 years with the club and after having won eleven trophies with the side.

Other improvements[43] were made, such as a tunnel for the players leading into the home and away dressing rooms and new dugouts on the far side of the pitch, as well as new terracing and access for disabled fans.

Spennymoor Town's biggest attendance at Brewery Field came in February 2013 when 2,670 fans turned out for a Northern Football League Division One game against Championship rivals Darlington.

Supporters of Spennymoor Town are drawn in from all over the North East and have fans located all over the world who follow the action through the Facebook and Twitter pages.

Spennymoor's local rivals are considered to be Bishop Auckland, one of the oldest members of the Northern League, who currently play at Heritage Park.
