Nasiruddin Chowdhury (Bengali: নাসিরউদ্দিন চৌধুরী; born 9 October 1979) is a Bangladeshi professional footballer who plays as a defender.

[4][5] In 2004, the Army were the runners-up at the Sher-e-Bangla Cup (losing to Narayanganj) and Nasir finished as the top-scorer with 5 goals.

After this encounter, Nasir decided to quit his job in the army and in 2008, he filed a petition with the authorities and returned home.

With the help of the then director of Muktijoddha Sangsad KC, Major General Amin Ahmed Chowdhury, he finally got a clearance from the army.

He scored twice against Chittagong Abahani during the 2013–14 season putting his team six point clear at the top of the table, in the end Sheikh Jamal went onto win their second league title that year.

In 2018, Nasir was caught in a controversy, as he took an advance of Tk 3 lakh from Abahani, confirming he would stay at the club; but later he joined newcomers Bashundhara Kings.

[15] However, his second stint at the club was disappointing, as an aging Abahani team failed to win the league title once more, losing out to Bashundhara Kings.

[17] The following year Abahani released all of there veteran players including Nasir, who went onto join Sheikh Russel KC in 2021.

Nasir captained Bangladesh at the 2013 SAFF Championship, where he injured his head after a collision with Indian defender Nirmal Chettri.
