This study examines how female football (soccer) fans use the social media platform Tumblr to interact and talk about their fandom, what purposes Tumblr serves for them, and why they prefer it to other social media platforms. As women are often marginalised in offline and online sports discourse, Tumblr’s football fandom was chosen to investigate how women experience their fandom on a platform with a mostly female and young user population. The results of 14 in-depth qualitative interviews with heavily invested female Tumblr users show that the fandom’s communication culture allows fans to interact in a variety of creative ways that involve the use of a specialist vocabulary. This Tumblr fandom is overwhelmingly female, which makes the interviewees feel that they can talk freely about football. Thus, Tumblr has the potential to serve as a safe space for female fans. Yet, its highly opinionated discussions and rivalries mirror those in the traditional football fandom. This study contributes to the literature that explores how women express their sports fandom online and demonstrates how they have found a niche in which to discuss their favourite sport on their own terms.
