2011 World Championships in Athletics – Men's 4 × 400 metres relay

The Men's 4 × 400 metres relay event at the 2011 World Championships in Athletics was held at the Daegu Stadium on 1 and 2 September.

After the first handoff, they were passed quickly by Ofentse Mogawane putting South Africa into the lead followed by Jermaine Gonzales of Jamaica.

Five time defending champion United States, running hurdlers Bershawn Jackson and Angelo Taylor, was a slow third place behind South Africa's Willem de Beer watching Jamaican Riker Hylton separate from the field, but Hylton tied up on the home stretch and the race tightened going into the final handoff.

Taking the baton in the unfamiliar third place, Silver medalist LaShawn Merritt ran a controlled race in lane one moving into position for one final surge on the home stretch.

South Africa anchor, hurdler L. J. van Zyl, held off Jamaica's Leford Green for the silver medal.
