Francis Howard Greenway (20 November 1777 – September 1837) was an English-born architect who was transported to Australia as a convict for the alleged crime of forgery.

On board the ship was the surgeon Dr John Harris who was to give Greenway his first private commission in the colony which involved extending his residence on his Ultimo estate.

Greenway’s works include Hyde Park Barracks, extensions to First Government House, the stables for a projected new Government House (condemned for their ‘useless magnificence’ by a visiting British official, the building is now home to the Sydney Conservatorium of Music),[8] and St James' Church, Sydney, which was chosen as one of Australia’s only two man-made ‘treasures’ by Dan Cruickshank in the BBC series Around the World in 80 Treasures.

[9] He submitted designs for the first Catholic church in Sydney, St Mary's but they did not match the ambitious scale envisaged by the priest Fr Therry, and were not proceeded with.

[10] Greenway fell into disrepute when Macquarie accused him of charging high fees whilst on a government retainer, and he was dismissed by the next governor, Thomas Brisbane, in 1822.

In 1835 he was destitute, advertising in the Sydney Gazette that "Francis Howard Greenway, arising from circumstances of a singular nature is induced again to solicit the patronage of his friends and the public".
