Kay Morley-Brown (née Morley, born 5 March 1963) is a British former athlete who competed in the 100 metres hurdles.

She was a member of the Cardiff Amateur Athletic Club and was coached by Malcolm Arnold.

After only qualifying for the final as a fastest loser, she won the gold medal in a lifetime best of 12.91 secs, with Gunnell second and Lesley-Ann Skeete third.

This made her only the third British woman in history, after Shirley Strong and Gunnell, to run under 13 seconds for the 100 metres hurdles.

Outdoors, she won her third UK National title with a narrow victory over Lesley-Anne Skeete, before finishing second to Sally Gunnell at the AAAs Championships (which were also the UK Olympic trials) earning Olympic selection.
