William Henry Allan Munro (1856–1913) was an architect in Queensland, Australia. Some of his works are now heritage-listed.
Munro was born in Inverness, Scotland in 1856, the son of tailor George Munro and his wife Mary (née Allan). He trained under Matthews & Lawrie.
In 1886, he emigrated to Queensland and worked as an architect for Rooney Brothers of Townsville. There he won the competition for the Queensland Hotel and was taken into partnership by Walter Eyre in 1887. After the firm ceased trading in 1892, Munro worked for the government but also undertook private contracts.
Munro died on 23 February 1913 in Brisbane. He was buried on 24 February 1913 in the South Brisbane Cemetery.
