Nuno Oliveira (23 June 1925 – 2 February 1989) was a Portuguese equestrian, horse trainer and dressage instructor. His teachings have inspired riders and trainers all over the world to adopt the 'baroque' or 'classical' style of working with the horse; an art which goes back hundreds of years and encompasses the fundamentals which most 'modern' disciplines can be traced back to.
