The Great Comet of 1823, also designated C/1823 Y1 or Comet De Bréauté-Pons, was a bright comet visible in the last month of 1823 and the first months of 1824.

It was independently discovered by Nell de Bréauté at Dieppe on December 29, by Jean-Louis Pons on the morning of December 30, and by Wilhelm von Biela at Prague on the same morning.[1] It was already visible to the naked eye when discovered: Pons initially thought he was seeing smoke from a chimney rising over a hill, but continued observing when he noticed it did not change appearance. He was later to note that the comet was, puzzlingly, more easily visible to the naked eye than through a telescope.[2]

The comet was particularly known at the time for exhibiting two tails, one pointing away from the Sun and the other (termed an "anomalous tail" by Harding and Olbers)[3] pointing towards it.

Caroline Herschel recorded an observation of the comet on January 31, 1824 as the last entry in her observing book.[4]

Pons was also the last astronomer to detect the comet, on April 1, 1824.
