Pamela Kilborn-Ryan, AM MBE (born 12 August 1939) is a former Australian athlete who set world records as a hurdler. She was born in Melbourne. For three years, she was ranked as the world's top woman hurdler.
Kilborn began competing in athletics in Melbourne during the late 1950s. She competed for the University High School team, under coach Henri Schubert alongside her good friend Judy Amoore (later Pollock).
In 1960 she attempted to gain selection for the 1960 Summer Olympics but could only place third in the Australian Championships with only the first two athletes chosen. She was reputedly so ill during these Championships that she had to be assisted on the medal dais.
At the 1962 British Empire and Commonwealth Games in Perth, Australia, Kilborn became one of the stars of the Games, upsetting world-record holder Betty Moore in the 80 m hurdles race before winning the long jump contest ahead of two countrywomen Helen Frith (silver) and Janet Knee (bronze).
In 1967 she broke Christine Perera's unofficial 100 m hurdles world record of 13.7 seconds and improved it twice up to 13.3 seconds in 1969.
Having been undefeated since the 1964 Olympics, Kilborn was the favourite for the 1968 Summer Olympics in Mexico City. At the Games she was hampered by a shoulder injury and could not overcome her surprising teenage countrywoman Maureen Caird in the rain-affected final.
In 1970 the international hurdling distance was extended to 100 metres and, competing at the British Commonwealth Games, she beat Caird to take yet another gold medal. Her three successive golds was the most ever won by any athlete at the Commonwealth Games. Earlier in the Games she was chosen to carry the Australian standard in the Opening Ceremony; the first time a woman had been awarded this honour.
After a brief retirement, she returned to the track for one last Olympic campaign in 1972. She set a World Record of 12.5 (12.93 automatic timing) shortly before the 1972 Olympics in Munich, but could only run fourth in the Olympic final.
Kilborn was made a Member of the Order of the British Empire (MBE) in 1971 and a Member of the Order of Australia (AM) in 2008. She was inducted into the Sport Australia Hall of Fame in 1985 and received a Centenary Medal in 2001.
Kilborn set multiple Australian records in seven different events during her career: 80 metre hurdles, 100 metres hurdles, 200 metres hurdles, Long Jump, Pentathlon, 4 x 200 metres relay, and 4 x 220 yards relay.
Over 80 metres hurdles, Kilborn set two official world records in 1964 and 1965.
In the 100 metres hurdles, she set one official world record at Warsaw on 28 June 1972.
At 200 m hurdles, Kilborn-Ryan set four official world records between 1969 and 1971, with a best of 25.7.
