2023 World Athletics Championships – Men's 4 × 100 metres relay

The men's 4 × 100 metres relay at the 2023 World Athletics Championships was held at the National Athletics Centre in Budapest on 25 and 26 August 2023. It was the 19th edition of this relay at the World Athletics Championships since 1983.

After procedure modifications, the fastest qualifiers were assigned outside lanes, thus more favorable, wider turns. With one of the fastest starters in history, 2019 100m champion Christian Coleman out of the blocks, USA was making up the stagger on Japan, the only team to its outside. A couple of lanes inside, Jamaica's Ackeem Blake was gaining on South Africa between them. USA clearly passed first to 2022 100m champion Fred Kerley, Jamaica passed late in the zone to Oblique Seville but the same time as GBR passed to Zharnel Hughes. USA made the second pass from Kerley to Brandon Carnes ahead, but they were slowed by two attempts to transfer the baton. Jamaica to Ryiem Forde and GBR to Adam Gemili passed about even, and Italy's quick pass from Olympic Champion Marcell Jacobs to Lorenzo Patta put them into contention. Through the turn, Jamaica and Italy gained ground. Jamaica passed to their surprise National Champion Rohan Watson less than a metre behind USA. But USA had the double sprint winner Noah Lyles on anchor. Lyles opened up a 4 metre gap on his leg for a clear American victory. Italy passed to Filippo Tortu a metre down to Jamaica, but Tortu reversed that and gained a couple of metres for a clear second. Watson was able to hold off GBR's Eugene Amo-Dadzie and Japan's fast closing Abdul Hakim Sani Brown to retain bronze. It was Jamaica's first 4x100 medal since the retirement of Usain Bolt. Upon crossing the finish line, Lyles held up 3 fingers for the cameras to celebrate his third gold medal at these championships.
