Zambia competed in the 2008 Summer Olympics in Beijing, the People's Republic of China, sending eight athletes to the competition.

The use of Simplified Chinese stroke count placed it last before the host nation in the Parade of Nations as it takes sixteen strokes to write the first character and four to write the second.

One of the two Zambian athletes managed to advance beyond the opening heats, Rachael Nachula in the women's 400 metres.

Both Zambian swimmers participated in the 50 metre freestyle, but neither of them managed to advance past the first round.

Qualifiers for the latter rounds of all events are decided on a time only basis, therefore positions shown are overall results versus competitors in all heats.
