Festival spokesman Terry Harris says that to his knowledge, no Alberta premier has accepted an invitation before.
Redford's official itinerary for next week states the premier will greet the Edmonton Pride Festival on Saturday afternoon in Sir Winston Churchill Square, which is in front of City Hall.
Harris says the event in the square immediately follows the annual pride parade.
During the provincial election campaign in April, an online video surfaced of Opposition Wildrose Party candidate Allan Hunsperger claiming homosexuals would burn in a lake of fire.
Redford said at the time that if Hunsperger was a Progressive Conservative, she would have removed him from her team.
