The delegation consisted of seven competitors; three track and field athletes Gerald Phiri, Prince Mumba and Chauzje Choosha, one each in Boxing and Judo (Gilbert Choombe and Boas Munyonga) and two swimmers, Zane Jordan and Jade Ashleigh Howard.

Phiri received a bye in the men's 100 metres and was eliminated at the first round stage and recorded his best time of the 2012 athletic season.

Mumba and Choosha were both eliminated from the competition in the parliamentary heats, and Choombe was defeated by Australian Jeff Horn in Boxing's round of 32.

[1] The country sent athletes Gerald Phiri, Prince Mumba and Chauzje Choosha, boxer Gilbert Choombe, judoka Boas Munyonga and swimmers Zane Jordan and Jade Ashleigh Howard to London.

[7] The country's NOC secretary general Hazel Kennedy said it was "comforting" that the team sent athletes who had qualified on merit rather than a majority on wildcards.

[8] The team elected to train at the Palace of Art Centre for Sport Excellence and Scotstoun Stadium in Glasgow for two weeks.

[17] Mumba qualified for the London Games, as his personal best time of one minute and 46.14 seconds met the "B" standard for the men's 800 metres .

[3] Choosha qualified via a wildcard and replaced long-distance runner Tonny Wamulwa, who withdrew before the opening of the Games because of injuries sustained in a road traffic accident on 9 July.

[7][4] She took part in the women's 100 metres in the preliminary round on 3 August and was drawn in heat one, finishing fourth out of eight athletes, with a time of 12:29 seconds.

Horn began strongly by performing quick shots at Choombe who attempted to react by throwing back some punches but missed most of them.

When the ball rang to signal the start of the match, Munyonga held Nakai by the leg and placed him onto the corners of the mat.

[27] Zane Jordan was the only member of the Zambia team to be a two-time Olympian, having competed at the Beijing 2008 Summer Olympics.

[3][23] Like Jordan, Howard qualified after receiving a universality place from FINA, her personal best time of 1 minute, 1.24 seconds was outside the "A" and "B" qualification standard.

[23] Howard took part in heat four of the women's 100 metre freestyle, which was held on 1 August, finishing first out of seven swimmers, with a time of 59.35 seconds.
