Alexander Joseph Ranald Shaw FRSA (born 1971) is an English philosopher.

He serves as chairman of the Latin Mass Society, an organisation devoted to propagation of the Catholic Church's Tridentine Mass, and as president of Una Voce.

He was a tutorial fellow in philosophy at St Benet's Hall, Oxford,[1] until its closure in September 2022.

[3] A traditionalist Catholic, Shaw was a signatory of the 2017 "filial correction" Correctio filialis de haeresibus propagatis, which ascribed heretical content to Pope Francis's apostolic exhortation Amoris laetitia.

Shaw was also an early critic of Pope Francis’s motu proprio Traditionis custodes, which abrogated permissions for celebration of the Tridentine Mass.
