William Herbert Guthrie-Smith FRSNZ (13 March 1862 – 4 July 1940) was a New Zealand farmer, author and conservationist.

In September 1882 he leased Tutira, a sheep station in central Hawke's Bay, which was his home for the rest of his life.

[2] After the First World War he met Beatrix Dobie who was exhibiting her work at the Canterbury Society of Arts Gallery.

They formed the connection that would lead to her providing the illustrations for his book Tutira: The Story of a New Zealand Sheep Station.

The transformation of New Zealand from bushlands to grasslands farming is anatomised in this close examination of the effects of plant and animal introductions on one piece of Hawke’s Bay.”[7]Before his death in 1940 he revised and added to Tutira.
