Boardman is a census-designated place in Boardman Township, Mahoning County, Ohio, United States, a suburb directly south of Youngstown. Boardman is one of two major retail hubs in the Mahoning Valley. Boardman is a large, sprawling suburb. It is a busy community south of Youngstown composed of many chain restaurants. It is one of the main shopping and retail centres for the greater Youngstown area. Its main competitor is the northern 422 "Strip" in Niles, Ohio (a similar suburb of Warren, Ohio).
While much development is centred on the 224 corridor, a new area of development (even further south) is surging along the South Avenue artery which parallels the southern extension of Interstate 680 between its Midlothian and Western Reserve Road exits. Boardman abuts one of the Youngstown area's most popular attractions, Mill Creek Park. Within the park grounds, there is an 11-acre (45,000 m²) rose garden, several small waterfalls, a lily pond with geese and turtles, marshlands, and Lanterman's Mill, where grain is ground daily. In addition, there is a 36-hole golf course.
Boardman has a population of over 35,380 people. Boardman also forms part of the wider Youngstown-Warren-Boardman metropolitan area which has a population of over 565,773 people.
