Founded in 2022, RainbOs is the official LGBTQ+ supporters’ group for Leyton Orient. The group emerged from a collaborative initiative between the club and its community to ensure that Brisbane Road remains a welcoming environment for all. By creating a dedicated network for LGBTQ+ fans and their allies, they have established a visible and supportive presence within the historic East London club.
The primary aims of RainbOs are centred on visibility and inclusion. They strive to ensure that every supporter, regardless of their sexual orientation or gender identity, feels safe and respected while cheering on the O’s.
RainbOs actively participate in national movements such as the Football v Homophobia campaign. They also represent Leyton Orient at local events like Waltham Forest Pride and work with player ambassadors to promote inclusivity throughout the squad. Their current efforts focus on expanding their reach within the local community and delivering workshops to the club's youth development teams to inspire the next generation of inclusive fans.
