Labour Day, also known as International Workers' Day, is a national holiday in Colombia which is celebrated annually on May 1. This date is recognized by most countries worldwide as a day to honor and respect the contributions of workers. Labour Day in Colombia is known as 'Dia de los Trabajadores' and it is a day off for the general population, with most businesses, schools, government offices, and shops closed in observance of the holiday. Colombia began officially celebrating Labour Day in 1913, nearly two decades after it was recognized internationally.

On Labour Day, massive marches and parades are commonly organized by trade unions and workers' rights groups across the country. Workers, students, and generally the support for labor rights come out to take part in numerous demonstrations throughout the cities. These occasions serve as platforms to voice workers' rights and other related issues, voicing demands for improved working conditions, higher wages, and fair treatment. Public figures and politicians also often participate, showing their solidarity with workers nationwide, and giving speeches in support of workers' rights.

However, Labour Day in Colombia is not all about demonstrations and protests, it also offers a time for people to enjoy leisure activities. Traditional music from different regions of the country is played, dances, and theatrical performances often take place, making the holiday a cultural event as well. Like many places worldwide, Labour Day in Colombia serves both as a potent symbol of workers' struggles and victories, and as a universal celebration of the dignity and worth of labor.
