Glenvil is a village in Clay County, Nebraska, United States. The settlement was formerly also known as Glenville. The population was 267 at the 2020 census. It is part of the Hastings, Nebraska Micropolitan Statistical Area.

Glenvil was founded in 1873 when the St. Joseph & Denver City Railroad was extended to that point.

The Glenvil post office, first established in 1873 (in the year the settlement was first surveyed) was spelled Glenville until 1914.

Glenvil's population peaked at about 300 in the 1920s, and fell to about half that in 1998.

Glenville's first school was organized during 1871-72 and, like other rural schools, was housed in a wood-frame building. It was demolished by a tornado and rebuilt in 1882. The Glenville School, the first substantial school in the village, operated from 1903 to 1995 and is listed on the National Register of Historic Places.

Glenvil received national attention in 1997 when residents wrote letters to celebrities asking for money to help build a new playground. Letters were sent to billionaire Warren Buffett, comedian Robin Williams, talk show hosts Jay Leno, David Letterman and Oprah Winfrey; and Microsoft Chairman Bill Gates asking for financial help. Gates was the only one who responded as he wrote back and included a check for $5,000. Less than a month after Gates donated the $5,000 Merle Hinrichs, chairman of Asian Sources Media in Hong Kong, mailed a check for $20,000 after project organizers said they needed more money for playground equipment. Hinrichs attended school in Glenvil.

According to the United States Census Bureau, the village has a total area of 0.17 square miles (0.44 km), all land.
