Sir Arthur Dudley Dobson was a New Zealand surveyor, engineer and explorer. Born in London, he came to Lyttelton, New Zealand, in 1850 on one of the First Four Ships. He is best known for taking the first party of Europeans over Arthur's Pass.

Arthur's Pass is a mountain pass in the Southern Alps of the South Island of New Zealand. The pass sits 920 metres or 3,020 feet above sea level and marks part of the boundary between the West Coast and Canterbury regions. Located 140 km from Christchurch and 95 km from Greymouth, the pass comprises part of a saddle between the valleys of the Ōtira River and of the Bealey River. Arthur's Pass lies on the border of the Selwyn and Westland districts.
