Jhirk, also spelled as Jerruck,[1] is a small town on the right bank of the Indus River in the Thatta district of the province of Sindh, Pakistan.

The headquarters of the Indus Flotilla was initially in Jhirk, near Kotri, before relocating to Mithankot in Rajanpur district and later to Makhad in Attock.

Hassan Ali Effendi, the renowned educationist who played a key role in establishing Sindh Madrasatul Islam, worked with the Indus Flotilla in his early years while learning English.

Sir Charles Napier initially established Jhirk as the headquarters for the British Army in Sindh when he arrived in the region, which was part of the Bombay Presidency at that time.

His eldest son, Jinnahbhai Poonja, who was Muhammad Ali Jinnah's father, married Sheeren Bai, the daughter of Moosa Jumo, in 1874.

Due to the lack of water in the Kotri River, most residents live below the poverty line, leading to widespread abandonment of the area.

Many graduates and young people from the Mallah fishing community either sell brambles or subsist on minimal rural incomes.
