Giltner is a village in Hamilton County, Nebraska, United States. The population was 352 at the 2010 census.

According to the United States Census Bureau, the village has a total area of 0.39 square miles (1.01 km), all land.

In 1886, the Lincoln Land Company purchased land in the Union township. The Lincoln Land Company's business was to purchase land along the railroad and develop towns along the line. In May, a town was platted and named "Huntington", after an employee's home town in Pennsylvania.

In February 1887, the post office asked that the town's name be changed, due to the original name's similarity to Hartington, Nebraska. The town was accordingly given the name "Bromfield". By 1890, there was a local newspaper called the Bromfield Bulletin, as well as a number of stores and services, a lumberyard, two grain elevators, a school, a saloon and a church. At this time, the population of Bromfield was just under 200 people.

The town was renamed again in 1895, again at the request of the post office, and again because of its similarity to that of another town: Bloomfield, Nebraska. The new name was chosen to honor H. M. Giltner, the minister who had established the town's Presbyterian church.

Giltner was home to minor league baseball. In 1903, the Giltner team played as charter members of the short–lived Central Nebraska League, an Independent level five-team league. The Central Nebraska League folded after the 1903 season.
