Multiracial undergraduates are coming of age when assertions of a post-racial era claim the post-civil rights multiracial population as its proof, which is part of the socio-historical context of the campus racial climate. Given that campus racial climate research has been silent about multiracial students, the purpose of this study is to explore multiracial undergraduates' perspectives of the climate. Interviews of fourteen undergraduates at a public university in the western United States reveal the prevalence of multiracial microaggressions in the campus racial climate, indicating both a negative racial climate for most and evidence against claims to a postracial society. Educators are encouraged to incorporate multiraciality into existing curricula, programs, and other educational avenues that already address matters of race and racism in U.S. contexts. Future analysis must also explore variation within the multiracial climate and why some students may experience a more negative climate than others.
