Sir Arnold Robinson is a fictional character in the 1980s British sitcom "Yes Minister" and its sequel, "Yes, Prime Minister". He was played by John Nettleton. He attended Baillie College with Sir Humphrey and shares the same views on the running of the country, the Government and the Civil Service.

In "Yes Minister", Sir Arnold holds the position of Cabinet Secretary. In the last episode, "Party Games", he retires and is succeeded by Sir Humphrey Appleby, then Permanent Secretary for the Ministry of Administrative Affairs.

In "Yes, Prime Minister", while now retired from the Civil Service, he is often sought for advice by Sir Humphrey and, on one occasion, by Jim Hacker, when he suspects Sir Humphrey of being a spy (of which he is cleared), in One of Us.
