Kathryn Evans (born 5 August 1981) is an English former competitive swimmer who represented Great Britain in the Olympic Games.

Swimming in heat five, she rounded out a field of eight swimmers to last place and twenty-fourth overall in 2:19.41, just 5.58 seconds behind defending Olympic champion Yana Klochkova of Ukraine.

Teaming with Melanie Marshall, Karen Pickering, and Lisa Chapman in the final, Evans swam a second leg, and posted a lifetime best of 54.33.
