The Men's 4 × 100 metres relay at the 2005 World Championships in Athletics was held at the Helsinki Olympic Stadium on August 12 and August 13. Great Britain just beat Jamaica (38.28, SB) and Australia (38.32, SB) to bronze medal position. The United States' team did not participate in the final, having bungled their first relay stick handoff in their qualification heat the previous day.
