Teja Dashmi is a festival celebrated in Rajasthan, India, and is dedicated to a folk deity called Tejaji or Veer Teja, who is considered an incarnation of Shiva. The festival is celebrated on Bhadrapad Shukla Dashmi, which is the tenth day of Shukla Paksha of Bhadrapad, according to the Hindu calendar. In 2023, Teja Dashmi will be celebrated on September 25th.

Tejaji is a folk lord of the Rajasthan region who is considered a form of Lord Shiva. He is known for his bravery and is worshipped for health and wealth. Legend has it that Tejaji lost his life protecting cattle from hunters, and during his dying moments, he allowed a snake to bite his tongue. As a result, the snake granted a blessing that anyone who sought his blessings would not die from snakebite. On Teja Dashmi, people in Rajasthan still observe a fast in honor of Tejaji.

During Teja Dashmi, people visit Tejajis temples to pray and offer parasadi (devotional food) and milk as part of worship rituals. The festival is celebrated with great fervor in several locations in Rajasthan, Haryana, Uttar Pradesh, and Madhya Pradesh.

In rural areas of Rajasthan, people have been celebrating Teja Dashmi to seek Veer Tejas blessings for centuries. The biggest celebrations are held in Tejaji temples in the villages of Kharnal, where Tejaji was born, Paner, where he got married, and Sursura, where he died and attained nirvana.
