Trichur Pooram is the annual temple festival of the town of Trichur Kerala India . It is one of the most colourful temple festival of Kerala which attracts large masses of devotees and spectators from all parts of the State and even outside.

Thrissur Pooram is celebrated at the premises of the Vadakkunnathan Temple, situated on a hillock (Thekkinkadu maidan) right in the centre of the city, on the Pooram day in the month of Medom (April-May). Processions of richly caparisoned elephants accompanied by percussion ensembles from various neighbouring temples culminate at the Vadakumnathan temple. The most impressive processions are those Thriuvambadi Bhagavathyfrom theThiruvambadi krishna temple and the [ParamekkavuBhagavathi]] from Paramekkavutemple.. The celebrations which last for over 36 hours includes parasol displays and firework shows.

This festival was introduced by Sakthan Thampuran, the Maharaja of the erstwhile Cochin State in the late eighteenth century. Perhaps, there is no other festival in Kerala that draws such an unbelievable number of people to a single event. However Vadakkunnathan is a mere spectator at this festival, lending its premises and grounds for the great event. The pooram festival is also well known for the magnificent display of fireworks. Fire works start in the early hours and the dazzling display last three to four hours.

The Pooram Festival is celebrated by two rival groups representing the two divisions of Thrissur Paramekkavu and Thiruvambadi vying with each other in making the display of fireworks grander and more colourful. Each group is allowed to display a maximum of fifteen elephants and all efforts are made by each party to secure the best elephants in South India and the most artistic parasols, several kinds of which are raised on the elephants during the display. Commencing in the early hours of the morning, the celebrations last till the break of dawn, the next day.
