Royal Manitoba Winter Fair (RMWF) is an annual agricultural fair near the end of March, hosted by the Provincial Exhibition of Manitoba in the Keystone Centre in Brandon, Manitoba, Canada. The largest event held in Brandon, and one of the largest agricultural events in Western Canada, the RMWF is traditionally held each year during Manitoba's academic spring break. In 1970, it received royal patronage from Queen Elizabeth II, and is one of only two fairs in Canada with royal patronage. Events at fair include show jumping and heavy horse competitions, livestock sales and displays, and hands-on agricultural awareness programs as well as exhibits and entertainment.
