Alejandro Cartagena (b. 1977, Santo Domingo, Dominican Republic) is a Dominican-born Mexican photographer based in Monterrey, known for formally striking, socially incisive series on suburban sprawl, the US-Mexico border and economic inequality, including the celebrated photobook Carpoolers (2014). His first museum retrospective, Ground Rules, opened at SFMOMA in 2025, and he serves as lead curator at Fellowship, the platform for photography and AI-based art. In Photographic Structures (GAN) (2025), he trained a generative adversarial network on faces cut from thousands of discarded vernacular photographs salvaged from Mexico City landfills, producing half-formed visages that slip between presence and absence.
