Inspired by new feminist materialism, this paper seeks to reimagine existing knowledge of girls, sexuality and playgrounds by considering how the socio‐material reality may unlock girls' capacities for what is possible through play. Focusing on semi‐structured interviews of girls (aged 12–13), the paper draws attention to the playground as an ‘assemblage’ of human and non‐human matter that connect to illuminate other ways of being, feeling and doing. We argue that the assemblage not only creates spaces for girls to disrupt hetero‐patriarchal ideologies but simultaneously serves to reinforce them. Interventions require attention to the oppressive materialities that underpin play.
