Labour Day in Myanmar (formerly known as Burma) is a public holiday, celebrated on the 1st of May each year. It is a day set aside to honour the contribution of workers across the country. Myanmar, being a predominantly agrarian economy, celebrates this day by acknowledging the hard work, effort, and dedication of its labor force that contributes to the country's social and economic progress.

The origins of Labour Day go back to the 1880s in the USA, when labor unions began to demand better working conditions and an eight-hour workday. Adopted internationally, it serves as a reminder of workers' rights and social achievements of the labour sector. In Myanmar, the day is often marked by rallies and marches in various cities, held by different unions and labour parties to express worker solidarity and to draw attention to workers' rights and relevant issues.

Over the years, Labour Day in Myanmar has also become a focus for expressions of discontent with labour rights and conditions. It has become a platform for advocating for policy changes, such as improved labour laws and working conditions. Despite the serious undertone, the day also offers a chance for workers to relax and enjoy time with their families, with some families participating in public or private celebrations, typically involving leisure activities and feasts. It's a mixture of reflection on labor rights and achievements and a celebration of the labor force of the nation, recognizing their continuous hard work and dedication.
