Golden Cygnet (1972 - 1978) was a racehorse who was described in the 1979 Irish Racing Annual by legendary Irish trainer Vincent O'Brien as "the best hurdler I've ever seen." His hurdling career lasted less than 5 months, as a result of the fatal injury he sustained in the 1978 Scottish Champion Hurdle.
