Henry Lyall Hall (22 July 1861 – 23 May 1935) was an Australian politician, serving as the member for Perth in the Legislative Assembly from 1897 until 1901.
In 1896 he was elected to the North Ward of Perth City Council for a two-year term, and after joining the governing Forrest party, he won the seat of Perth in the Legislative Assembly at the 1897 elections against Stephen Henry Parker.
During this time, he was also active in advocating for the establishment of Hyde Park, then known as Third Swamp and used as a camping ground for travellers, to be converted into public gardens to allow citizens to better enjoy Perth's prosperity.
After 1907, he became an investor and speculator in real estate and was a member of the Wembley Park progress association.
He died on 23 October 1935 at St John of God Hospital in Subiaco, and was buried in the Anglican section of Karrakatta Cemetery.
