Vishwakarma Puja, also known as Vishwakarma Jayanti or Vishwakarma Day, is a festival dedicated to Lord Vishwakarma, the Hindu deity of architecture and craftsmanship. The festival is celebrated primarily in India, typically around September or October, on the last day of the Indian Bhadra month, which is also regarded as the Vishwakarma Jayanti.

Lord Vishwakarma is revered as the divine engineer and architect of the universe, and the creator of many palaces, weapons, and vehicles of the gods. The festival is especially observed in industrial areas, factories, workshops, and other places related to manufacturing and construction. Artisans, craftsmen, mechanics, smiths, welders, industrial workers, and others in related fields worship Lord Vishwakarma on this day, seeking his blessings for a successful career, safe working conditions, and a better future.

The rituals include the offering of prayers, pujas, and yagnas to invoke the deity. The tools, machines, and workplaces are cleaned, decorated, and worshipped as a mark of respect to Lord Vishwakarma and to pray for a better output from their tools. Following the prayers, community lunches and cultural programs are usually organized.

Vishwakarma Puja emphasizes the significance of workmanship, crafts, and industrial development, and encourages workers to take pride in their work and strive for excellence.
