World Toilet Day (WTD) is a campaign to motivate and mobilize millions around the world on issues of sanitation. Originally established by the World Toilet Organization in 2001, this day to draw attention to global sanitation issues is marked each year on November 19. Since 2001, World Toilet Day has grown in scope and recognition by global partners. In 2013, the United Nations (UN) passed a resolution recognizing WTD as an official UN international day.

It was estimated in 2015 that 2.4 billion (about 1 out of 3 people) lack access to improved sanitation facilities, and just under 1 billion continue to defecate openly.Sanitation is a human right, just like the human right to water. Lack of access to sanitation, impacts on health, dignity, and safety.
