Syed Muhammad Ishaq (Bengali: সৈয়দ মুহম্মদ এছহাক; 1915 – 1977) was a Bangladeshi Islamic scholar, author, mufassir, debator and educationist.

[1] Ishaq was born in 1915 to a Bengali Muslim family of Syeds in the village of Pashurikathi in Char Monai, located to the east of the Kirtankhola river in Backergunge District, Bengal Province.

He then became a student of Muhammad Ibrahim of Ujani at the Jamia Islamia Ibrahimia in Kachua, Chandpur, where he furthered his Qur'anic studies.

[citation needed] Among his students were Syed Fazlul Karim, Muhammad Abul Bashar of Shahtali and Azharul Islam Siddiqi of Manikganj.

For the entirety of the nine-month war, several government officials based in Barisal would shelter themselves with their families at the Charmonai Madrasa.
