In this ethnography of Bangladeshi men living and working in South Africa, I draw on the intersection of three sets of literatures—masculinities studies, mobility studies, and the emerging body of work on migrant masculinities— to argue that migrant mobility shapes and is shaped by relational performances of racialized masculinities. I analyze three particular moments of such “mobile masculinities.” The first is in the home country wherein migration is seen as a mandatory rite of passage into manhood. The second moment is in transit, where the relational masculinity of migrant men and “traffickers” (men who smuggle migrants across borders) is performed and (re)made. The final moment is in South Africa, wherein we observe two contrasting forms of masculinities: hyper masculinity (the idealization of violence and misogyny) and Ummah masculinity (the immersion in God and Islamic Ummah). Both kinds of masculinity in the final moment are attempts by the migrants to recuperate masculinity within a situation of extreme powerlessness. This article invokes the need for mobility research within gender studies, and an attention to a complex, processual construction of identities wherein gender, race, and other differences define the identities of migrants but also the discourses and narratives of masculinities.
