Mark Rashid is an American horse trainer and clinician from Colorado. Practicing within the western riding tradition, Rashid's philosophy involves understanding the horse’s point of view and solving difficult problems with communication rather than force. His methodology emphasizes the relationship between horse and rider as a partnership, in which the horse willingly takes direction from the rider, rather than a dominant rider directing a submissive horse.
While Rashid is grouped as a practitioner within the field of natural horsemanship, he personally tends to avoid that classification and has publicly expressed discomfort with the term when applied to himself and to horsemanship in general. 
He has written a number of books on his philosophy, including Big Horses, Good Dogs, & Straight Fences, Horsemanship Through Life, Life Lessons from a Ranch Horse, Horses Never Lie, A Good Horse is Never a Bad Color, and Considering the Horse.
A unique aspect of Rashid's work is that he is also a practitioner of Yoshinkan aikido and applies its principles to the art of riding.
