Claud Buchanan Ticehurst (1881 – 17 February 1941) was a British ornithologist.
Born at St Leonards-on-Sea, Sussex, Ticehurst was educated first at Tonbridge School and subsequently attended St John's College, Cambridge.[1] Initially trained as a medical physician, he soon turned to the collection of birds, and made trips to Europe with John Lewis James Bonhote and Hugh Whistler for this purpose.
His collection of 10,000 bird skins was bequeathed to the Natural History Museum.
During World War I, Ticehurst served with the British Army as a surgeon, visiting Basra and Quetta, and afterwards became an authority on the birds of South Asia, following in the footsteps of Philip Lutley Sclater. He was working on a comprehensive publication regarding this topic with Hugh Whistler when he died in 1941. With Whistler's own passing two years later, the book was never published.
C. B. Ticehurst was the brother of ornithologist Norman Frederick Ticehurst (1873-1960).
