Shelbourne Women

In 1995 Shelbourne F.C. took over the women's football club Welsox F.C.. Welsox played in both the Civil Service League and the Dublin Women's Soccer League and had won the FAI Women's Cup in both 1992 and 1994. They were also DWSL runners-up in 1995. After coming under the Shelbourne umbrella, they also finished as FAI Women's Cup runners-up in 1997 and 1999 and were DWSL runners-up in 1998, 1999 and 2000. Future Republic of Ireland women's national football team manager Susan Ronan played for both Welsox and Shelbourne during this era. Following its integration into Shelbourne, the club was administered mainly, though not exclusively, by women on a voluntary basis while it received financial and logistical support from the men's club. However, in 2002, following a change in management and coaching staff, the original Shelbourne Ladies team disbanded and a core group of players moved to Templeogue United to merge with an existing girls' team.

After a five-year period of inactivity, Shelbourne Women's F.C. was revived in 2007 by Mick Neville, then serving as a director of coaching at Shelbourne F.C., and coach Keith O'Neill. The club initially fielded schoolgirl teams in the North Dublin Schoolboys/girls League before also joining the Metropolitan Girls League and the Dublin Women's Soccer League.

In 2015 Shelbourne Ladies merged with Raheny United's senior women's team. This effectively saw Shelbourne Ladies takeover Raheny United's place in the Women's National League. During the subsequent 2015–16 season, Shelbourne Ladies finished as runners-up in FAI Women's Cup, the WNL Shield and the Women's National League. All three competitions were won by Wexford Youths. However Shelbourne Ladies did win the WNL Cup after defeating UCD Waves 3–2 in the final at Richmond Park on 1 May 2016. In 2016 Shelbourne won the FAI Women's Cup after defeating Wexford Youths 5–0 in the final at the Aviva Stadium. The most notable individual performance to come out of the game was undoubtedly that of Shels' Leanne Kiernan, who scored a hat-trick and picked up the 'player of the match' award for her efforts.

The team won their first league championship when they finished the shortened 2016 season in first place. They qualified for the 2017–18 UEFA Women's Champions League with that title. In March 2019 Shelbourne announced a number of steps intended to boost "equality and parity of esteem for all of our players". They dropped the word Ladies from the women's team's name and moved WNL home games from the AUL Complex to the main stadium at Tolka Park.

The Reds hosted the first live league game which was broadcast on TG4 from Tolka Park on 2 October 2021 with the home side beating DLR Waves 1:0 with Alex Kavanagh scoring the only goal. Shels secured their second league title weeks later on a dramatic final day of the season as Shels won 3:2 to overtake Peamount United who threw away a two goal lead to lose 2:5. They were denied the double though in the FAI Cup final by Wexford Youths.

In 2022, the side went one better by securing the double. Facing Wexford away in a winner takes all final day decider, Shels strolled to a resounding 4:0 win to retain the WNL for the first time in their history. The cup was subsequently secured with a 2:0 win over Athlone Town in front of a record FAI Women's Cup final crowd.

Shels would miss out on league success in 2023 and 2024, finishing runners-up on both occasions, but would meet Athlone Town again in both the 2023 and 2024 FAI Cup finals. Shels would lose on penalties in the 2023 final, but would exact a form of revenge to deny Athlone the double in the 2024 final with a thumping 6:1 win.

Shels beat Athlone Town 2:1 in Tolka Park in the 2025 FAI Women’s President’s Cup, the season curtain raiser.

Shelbourne Women U18 won the 2015 WFAI Intermediate Cup, defeating St Catherine's 6–0 in the final. Shelbourne Women U18 also reached the semi-finals of the 2015 FAI Women's Cup, defeating two members of the Women's National League along the way. In the last sixteen they defeated Cork City 3–2 and in the quarter-finals they won 4–0 against Castlebar Celtic. In the semi-final they lost 4–0 to the Shelbourne Women senior team.
