Al-Hajj Abd-Allah Zaheeruddin Moazzem Hossein Chowdhury (1903 – 1967), popular known as Lalmia, was a Bengali Muslim politician.

His father was a wealthy Bengali Muslim merchant and zamindar who was engaged in the Indian freedom struggle.

The breakdown of Hindu-Muslim unity caused Lalmia's younger brother to become a leader of the Muslim League.

He played a key role in the Indian provincial elections, 1946 in which the Muslim League achieved a strong performance in Bengal, that ultimately led to the creation of Pakistan in 1947.

[6] Lalmia's younger brother Yusuf Ali Chowdhury (Mohan Mia) was the first General Secretary of the East Bengal Muslim League after the partition of India.

Lalmia's grandson Chowdhury Abd-Allah Quaseed is a prominent media and corporate personality in Bangladesh; he was a participant in the Commonwealth Common Purpose Leadership scheme sponsored by the late Prince Philip, Duke of Edinburgh and Anne, the Princess Royal.
