Walter John Trower FRSE (5 April 1804 – 24 October 1877) was an Anglican bishop.

In 1829 he became deacon of Chichester, from 1830 to 1832 was curate at Crowpredy and from 1832 was briefly a priest at Winchester before going to Petersfield and in 1834 going to Milland in Sussex.

He condemned everything that seemed consistent with ritualistic developments of the Oxford Movement and publicly opposed the eucharistic teaching of Bishop Alexander Forbes of Brechin.

[7] After a short period as sub-dean of Exeter Cathedral,[8] he was the Bishop of Gibraltar from 1863 to 1868.

[10] He gained some notoriety during the election of Frederick Temple as Bishop of Exeter when, on behalf of clergy who disapproved Temple's role as a contributor to the controversial Essays and Reviews, he instructed counsel to oppose the confirmation of the nomination which took place at St Mary-le-Bow, Cheapside, in December 1869.
