The 2023 IIHF U18 World Championship Division III was two international under-18 men's ice hockey tournaments organised by the International Ice Hockey Federation. The Division III A and Division III B tournaments represent the sixth and the seventh tier of the IIHF World U18 Championships. In the 'B' tournament, New Zealand finished in first place, securing promotion to the 'A' tournament next year. Returning to play, after missing three years of action, the kiwis needed Thailand to defeat Hong Kong on the final day to have a chance. The hosts, South Africa, finished last but will not face relegation as this is the lowest tier. It did, however, mark the second of three events to be hosted in Cape Town this year, a very unusual accomplishment for any IIHF nation.
