Friendships are vital to mental health and well-being. Understanding autistic individuals' lived experiences of friendship is necessary to support friendship development. A scoping review exploring autistic individuals' experiences of friendship was undertaken to understand their perspectives of friendship. Electronic database and manual reference searches identified twenty-two studies exploring autistic perspectives of friendship. Results were synthesised using a meta-ethnographic approach across the lifespan. Findings highlight the common and unique experiences of friendship among autistic individuals. While autistic individuals defined friendship based on homophily and propinquity, similar to non-autistic individuals, unique challenges including friendship insecurity, monotropism and efforts to conform to neurotypical social norms, leading to anxiety, were experienced by autistic individuals.
