García Garcés de Aza (Latin: "Garsias Garsie de Aza" ; "floruit" 1126–1159) was a Castilian magnate "renowned for his wealth and dullness", yet "a prominent figure in the later Andalusian campaigns of the Emperor between 1150 and 1157".
 His second name, "Garcés" (sometimes "García"), is a patronymic, indicating that his father was also named García, while his third name, "de Aza" is a toponymic frequently found in contemporary documents, in this case indicating that he held the "tenencia" of Aza.
 His father was in fact García Ordóñez, and his mother was the latter's second wife, Eva, probably a Frenchwoman.
 She re-married after García Ordóñez's death to Pedro González de Lara, and García Garcés was thus a half-brother of Eva's children by Pedro and closely allied with the House of Lara.
