Admiral Sir John Jeremy Black,, known as Jeremy Black or J. J. Black, was a senior Royal Navy officer. He commanded the aircraft carrier HMS Invincible during the Falklands War, and later served as Commander-in-Chief Naval Home Command from 1989 until his retirement in 1991.

HMS Invincible was the Royal Navy's lead ship of her class of three light aircraft carriers. She was launched on 3 May 1977 as the seventh ship to carry the name. She was originally designated as an anti-submarine warfare carrier, but was used as an aircraft carrier during the Falklands War, when she was deployed with HMS Hermes. She took over as flagship of the British fleet when Hermes was sold to India. Invincible was also deployed in the Yugoslav Wars and the Iraq War. In 2005, she was decommissioned, and was eventually sold for scrap in February 2011.
