Santiago Leyva (born October 19, 1988), better known by his stage name Fashawn, is an American rapper from Fresno, California. He first gained major attention after releasing his debut album Boy Meets World in 2009, which was produced entirely by Exile. The album received critical acclaim and landed him on the cover of XXL Magazine's Top 10 Freshmen issue in 2010. Since then, Fashawn has collaborated with other artists and producers such as Nas, J. Cole, Wiz Khalifa, Evidence, Murs, Aloe Blacc, Blu, The Alchemist, and 9th Wonder. In 2014, Fashawn performed the entrance theme to WBO welterweight champion Timothy Bradley's rematch against Manny Pacquiao.

On June 9, 2014, Fashawn signed to Nas' new label Mass Appeal Records. After years of anticipation, Fashawn released his second solo album The Ecology on February 24, 2015.
