Terence Christopher O'Brien (6 January 1936 – 30 December 2022) was a New Zealand diplomat. He led New Zealand in 1993 to a seat on the United Nations Security Council and played a strong role in helping to reshape New Zealand's perceptions of itself as a small but fiercely independent nation in the South Pacific.
