The Canadian Tulip Festival is a tulip festival held annually each May in Ottawa, Ontario, Canada. The festival claims to be the world's largest tulip festival, displaying over one million tulips, with attendance of over 650,000 visitors annually. Large displays of tulips are planted throughout the city, the largest of which are often in Commissioners Park on the shores of Dow's Lake, and along the Rideau Canal with 300,000 tulips planted there alone.

Tulip festivals are held in several cities around the world, mostly in North America, usually in cities with a Dutch heritage such as Albany, New York, Ottawa, Ontario; Gatineau, Quebec; Montreal, Quebec; Holland, Michigan; Lehi, Utah; Orange City, Iowa; Pella, Iowa; Mount Vernon, Washington; and Woodburn, Oregon, and in other countries such as New Zealand, Australia, India, and England. The tulips are considered a welcome harbinger of spring, and a tulip festival permits residents to see them at their best advantage. The festivals are also popular tourist attractions. The tulips are displayed throughout the cities. In certain years the peak of tulips does not coincide with the actual festival due to climatic conditions.
