Álvaro Rodríguez (fl. 1129–1166, died January 1167) was a Galician magnate during the reigns of Alfonso VII and Ferdinand II.

Álvaro was the son of Rodrigo Vélaz and Urraca Álvarez, perhaps a daughter of Álvar Fáñez and Mayor Pérez, daughter of Pedro Ansúrez. He married Sancha, an illegitimate daughter of Fernando Pérez de Traba and Theresa, Countess of Portugal. The earliest indication that the couple was married dates to 25 May 1150. After she was widowed, Sancha re-married to Pedro Alfonso. She died around 1182, having left Álvaro two sons, Rodrigo and Vermudo, and two daughters, Sancha and Teresa, who married Alfonso Ramírez.
