81st World Science Fiction Convention

The 81st World Science Fiction Convention (Worldcon), also known as 2023 Chengdu Worldcon, was held on 18–22 October 2023 in Chengdu, Sichuan, China. The co-chairs were Chen Shi, Ben Yalow, and Hongwei He.

Some fans and authors criticized choosing a Chinese city, citing human rights in China; about 100 authors wrote an open letter asking for the convention to be moved to another place. After the convention, some American websites commented that a number of Hugo Award ballots were rejected, and that the administrators excluded some nominees from the awards process for political reasons.
