The club was established in 1919 by demobilised soldiers returning after fighting in World War I. They joined the Northern Amateur League, going on to win the league title in their first season. They were also winners of the Northumberland Minor Cup, beating Byker St. Lawrence 2–1 in the final at Croft Park in Blyth in front of a crowd of around 5,000. A special train had been put on to bring fans up from Percy Main. Although tradition has the club's colours as claret and blue, at that time they were blue and white. The Northern Amateur League was won again the following season, with the club also winning the Tynemouth War Memorial Shield, defeating Whitley Athletic 2–1 after extra time at Hawkey's Lane before a crowd of almost 6,000. Following these initial successes, the club made an application to join the Northern Alliance, but were rejected. The club were subsequently runners-up in the league, the league cup and the Tynemouth Dispensary Cup in 1921–22. The following season saw them win the Tynemouth Dispensary Cup Final with a 1–0 win over New York United. Percy Main were then accepted into the Northern Alliance. However, they returned to the Northern Amateur League the following year due to the cost of travelling. They then won the Amateur League four times in a row, before moving to the Tyneside League in 1929. In October 1929, the club won the Amateur Shield at the North East Coast Exhibition in Newcastle upon Tyne, beating Stockton 3–1 in the final at St. James' Park They also reached the quarter-finals of the FA Amateur Cup in 1929–30, and were runners-up in the Tyneside League in 1932–33. In 1936–37 the club finished bottom of the league, which they left at the end of the following season, returning to the Northern Amateur League. In 1968 Percy Main rejoined the Northern Alliance, and in 1971–72 they won the League Cup. They were champions in 1980–81 and retained the title the following season. Although the club were runners-up the following season, they went into gradual decline, and were relegated from the Premier Division to Division One at the end of the 1990–91 season. In 1998–99 they were Division One champions, earning promotion back to the Premier Division. The club won the League Cup for a second time the following season, but were relegated to Division One again at the end of the 2005–06 season after finishing bottom of the Premier Division. They were Division One runners-up in 2009–10, resulting in another promotion to the Premier Division. Although the club were relegated again in 2013–14, they won Division One at the first attempt to earn an immediate promotion back to the Premier Division.
Ground
The club's ground was originally named Middle Row Park. In September 1925 a new dressing pavilion was opened. Although this was badly damaged by fire in early 1927, the club rebuilt it in time for the start of the 1927–28 season. In 1996 the ground was renamed Purvis Park after Alan Purvis, a former player, secretary and chairman who spent over 50 years at the club.
