Ivester is an unincorporated community in Grundy County, Iowa, United States.
Ivester is located on County Road T19 west of Grundy Center. It is in Melrose Township.
Founded in 1871, Ivester was named after Charles Ivester Keiter, the editor of The Atlas, a Grundy Center newspaper.
Ivester had a post office and a German Baptist Church in the late 1800s. Founded in 1871, the congregation is still active as the Ivester Church of the Bretheren. Circa 1915, Iverster was also the site of a general store, a blacksmith shop, and a creamery.
The post office at Ivester closed in 1904.
In 2019, after ten years of debate, the Grundy County Board of Supervisors approved a 35-mill wind farm in Ivester. The wind farm was controversial, drawing both detractors and supporters.
The Ivester site is sometimes referred to as a ghost town.
