Glenwillow is a village in Cuyahoga County, Ohio, United States.

As the population in surrounding areas, particularly the city of Solon, increased, Austin Powder was unable to test its explosive products.

It moved its manufacturing operations to Athens, Ohio, and closed its Glenwillow plant in 1972.

In the 1980s, the village installed infrastructural and utility improvements and added a 250-acre (1.0 km2) industrial park.

In the early 2000s, the village received significant investment through mixed-use development, including renovation of the former Austin Powder housing stock and general store into boutiques, a tavern, in conjunction with a new town center, village park and new housing in a town plan layout.

31.0% of all households were made up of individuals, and 13.9% had someone living alone who was 65 years of age or older.

The racial makeup of the village was 94.65% White, 4.23% African American, and 1.11% from two or more races.
