Álvaro Xavier da Fonseca Coutinho e Póvoas (Guarda 7 September 1773 – Guarda 29 November 1852), was a Portuguese military officer and noble, who served on the Miguelist side in Portugal's Liberal Wars.
Born in an aristocratic family, he joined the Portuguese Legion in 1808, but defected one year later to the Portuguese-British army.
He fought against the French as Lieutenant colonel, and ended the war in 1815 as Brigadier general.
After the war ended, he was dismissed from the army in 1834 and retreated from public life in his native Guarda.
