McPaul is a former townsite and unincorporated community in Fremont County, Iowa, United States.

The Kansas City, St. Joseph and Council Bluffs Railroad passed through McPaul in the late 1800s.

[2] Much of modern-day Interstate 29 covers the former townsite; only a few scattered houses remain.

The McPaul State Wildlife Management Area is located north of the townsite.

The McPaul exit off Interstate 29 was still closed, with visible standing water, in early October.
