Montgomery County is a county located in the U.S. state of Mississippi. As of the 2020 United States census, the population was 9,822. Its county seat is Winona.

The county is said to be named in honor either of Richard Montgomery, an American Revolutionary War general killed in 1775 while attempting to capture Quebec City, Canada, or for Montgomery County, Tennessee, from which an early settler came. In the latter case, it would have been indirectly named after John Montgomery, a settler in Montgomery County, Tennessee, who founded the city of Clarksville, Tennessee, in the same county.

The Big Black River passes through the southern part of the county, flowing southwest to its confluence with the Mississippi River south of Vicksburg.
