John Ferguson (c. 1777—September 5, 1832) was the 52nd Mayor of New York City from March to June 1815. He was also Grand Sachem of Tammany Hall.

Ferguson graduated from Columbia University in 1795, studied law, and became an attorney. He was active in politics as a Democratic-Republican, and became a political opponent of Dewitt Clinton.

He worked his way through the ranks to become leader, or Grand Sachem, of Tammany Hall.

In March, 1815 he was appointed mayor of New York City. He received the appointment with the understanding that he would resign in favor of Jacob Radcliff, and in return was appointed as Naval Officer of the Port of New York, a much more lucrative federal position, in which he served until his death.

From 1830 to 1832 he was a trustee of Columbia University.

Ferguson died in New York City on September 5, 1832.

Ferguson's daughter Louisa (1807-1845) was the wife of Robert Walter Weir. He was the grandfather of John Ferguson Weir, son of Robert and Louisa (Ferguson) Weir.
