The first home fixture took place on 5 November 1881, Rockcliffe were the visitors and this was the first game played under rugby union laws.

A large crowd attended to witness the first rugby game in the town, they were not disappointed as The Hotspur won by 1 goal and 3 touchdowns.

[citation needed] Fifty years then elapsed until the game of Rugby was re-introduced in the town in 1933 under the Presidency of Stan Anderson who as a Rockcliffe player, represented England in 1899.

For some years the club flourished with such stalwarts as Duncan Hodgson, Robert Hoigg and Harry Green forming the nucleus.

After the Second World War, efforts were made to revive the club but without success largely because there was no regular local source of players.

The club obtained the use of a field at Greensfield Moor as a pitch and accommodation for changing bathing and a clubroom was again made available at the Plough Hotel.

The game saw Alnwick claw back a 10-18 deficit to claim a thrilling 25-18 victory, with 5 minutes remaining the score was 17-18 in Pontefract's favour.

[10] After a four-season rebuilding period in Durham & Northumberland 1, Alnwick produced a young team, captained by the prolific try-scoring wing Andrew Shell.

The second half saw Keighley fight back to win 18–16 and seal promotion to the restructured level six league North 1 East.

They clinched promotion by finishing as champions of Durham & Northumberland 1 with a 10–28 victory against Medicals RFC in the final game of the season.

This was the first time since Northern and Team Northumbria in the 2010-11 season, that a newly promoted club from Durham & Northumberland 1 had avoided relegation from North 1 East.

The 2014/15 campaign proved to be more comfortable for Alnwick in comparison to the 2013/14 relegation battle with more games being won than lost, some notable performances and a terrific victory against Northumberland neighbours Percy Park.

The 2019/20 season finished with Alnwick narrowly avoiding relegation after the final table was completed using a best playing record formula.

Due to the COVID-19 pandemic in the United Kingdom, the Rugby Football Union (RFU) officially cancelled the season on 20 March 2020.

The annual Alnwick v Berwick fixture contested for the Claret Jug[16] takes place on the traditional derby date of Boxing Day.

In the 1983/84 season Alnwick reached the Northumberland Senior Cup final for the fifth time, as in the previous 4 occasions Gosforth were the opponents.

Strong defence during the last plays of the game allowed Alnwick to hold on for the victory and lift the Northumberland Senior Cup for the first time since 1983/84.

In July 2022, the Senior Women's team was reinstated by current co-captains Rosanna Curtis and Becky Dyson.

The season saw opponents including Whitley Bay Rockcliffe Roses, Peterlee & Horden, Acklam and Jarrow.

The 1st team pitch is floodlit, the first game under floodlights was a fixture against Northumberland County President's XV on Monday 29 October 1990.

[21] A major overhaul of facilities took place in 2012 resulting in new changing rooms being built along with a gym, improved toilets and showers, enhanced car parking, flood defense work and new advertising boards for the 1st team pitch.

[22] The new facilities were officially opened by Bob Reeves, president of the Rugby Football Union, on 19 October 2013 before the North One East clash: Alnwick 14 Wheatley Hills 8.
