Sir Arthur Morse KBE JP (Chinese: 摩士) (25 April 1892 – 13 May 1967) was the head of The Hongkong and Shanghai Banking Corporation during and after World War II.

Morse was sent to London by the then-Chief Manager of the bank, Sir Vandeleur Grayburn, to lead the bank and shift the headquarters to London to avoid the reserves being frozen in New York and San Francisco by the American authorities in the case of a Japanese take over in Hong Kong.

The Chief Manager, Sir Vandeleur Grayburn and his designated successor David C Edmondston died whilst prisoners in Hong Kong.

In 1943, the London Advisory Committee were empowered to act as a Board of Directors and he became the Chairman and Chief Manager of the bank.

In 1945, Morse supported a failed move to establish a popularly elected Municipal Council in the colony.
