Amar shonar Bangla,
Ami tomae bhalobashi.
Chirodin tomar akash,
Tomar batash,
Amar prane
Bajae bashi.
O ma, phagune tor amer bone
Ghrane pagol kore,
Mori hae, hae re,
O ma, oghrane tor bhora khete
Ami ki dekhechhi modhur hashi.
Ki shobha, ki chaya go,
Ki sneho, ki maya go,
Ki 達chol bichhaeechho
Boter mule,
Nodir kule kule!
Ma, tor mukher bani
Amar kane lage shudhar moto,
Mori hae, hae re,
Ma, tor bodonkhani molin hole,
Ami noyon ami noyonjole bhashi.
