Orissa  Society of Americas (OSA) is a premier vibrant non-profit Oriya cultural organization founded in 1969 at Boston, which has now spread over to many local chapters in North America. This organization is comprised of individuals interested in the Oriya language, literature and culture of a distinguished East Indian State  "Orissa".

OSA  Michigan Chapter, (MI-OSA), has been established since 1988 and is actively involved in promoting integration through social and cultural activities. The desire to cradle and nurture our rich culture even outside our homeland provided the impetus for the formation of this chapter. Particular emphasis is placed on sustaining our culture and heritage, supporting the society we live in and reinforcing the future generation with meaningful values of our life.
