Óscar José Ricardo Maúrtua de Romaña (born 7 February 1947) is a Peruvian diplomat and jurist who served as Minister of Foreign Relations of Peru from August 2021 to February 2022, under the presidency of Pedro Castillo.

[5] Maúrtua was appointed by president Alejandro Toledo as Minister of Foreign Relations for the first time on 16 August 2005, following the resignation of Carlos Ferrero's cabinet five days earlier, which prompted newly inaugurated foreign minister, Fernando Olivera, a controversial politician, to resign.

[6] He served under Pedro Pablo Kuczynski's premiership until the end to Toledo's presidency.

[7] Sixteen years later, Maúrtua would be called up to assume the ministry for a second time under Pedro Castillo's presidency and Guido Bellido's premiership, following Héctor Béjar's resignation amidst the political instability generated by the latter's unfortunate statements regarding the rise of terrorism in Peru, as he blamed the Peruvian Navy and the CIA on the matter.

[9] On 1 February 2022, Maúrtua was succeeded as minister by constitutionalist César Landa after President Pedro Castillo did not ratify him in his second cabinet reshuffle.
