Museum of Rajas', Folk museum in Zindabazar, Sylhet, Bangladesh.

The Museum of Rajas' occupies Raja-Kunjo, a tin-roofed building about a century old with a few rooms and a piazza in front, reached a few metres past the main gate. Portraits of Hason Raja and his son Dewan Eklimur Raja Chowdhury greet visitors at the entrance. Inside are two galleries: the main hall holds four large showcases and a 75 kg locker at its centre, while the second room displays published books and wooden furniture.

The building was once the residence of Dewan Hason Raja Chowdhury, a notable zamindar and mystic poet who lived from 1854 to 1922. After his lifetime, the property was transformed into a memorial to preserve his legacy and the cultural history of the region.

The museum's name honours the Raja family of Sylhet, and its two galleries centre on the zamindar and mystic poet Dewan Hason Raja Chowdhury (1854–1922). Gallery 1 holds a large collection of folk musical instruments alongside items from the film Hason Raja, which won the best movie award in 2002. Gallery 2 displays the books published on Hason Raja and his son Eklimur Raja, together with wooden furniture from the family.

The museum lies in Zindabazar, about 5 km from Sylhet Railway Station and 10 km from Osmani International Airport. From the main gate, visitors cross a few metres of courtyard to reach Raja-Kunjo, the tin-roofed building. Museum assistants conduct guided tours and welcome guests at reception.

At its opening in 2006, thousands of people played the Ek Tara simultaneously, creating a rare community experience. This event remains in local memory as a moment when an ancient instrument brought people together.
