Soľnička (Hungarian: Szolnocska) is a village and municipality in the Trebišov District in the Košice Region of south-eastern Slovakia.

In the late 17th century the plague devastated the village and three Csoma brothers - Janos, Gyorgy and Istvan were sent from the neighboring village of Lelesz, now Leles, Slovakia to repopulate the town.

After the World War II, the village become a part of newly formed Czechoslovakia.

The village and most of the region was again a part of Hungary from 1938 to 1945 when it again reverted to Slovak control.

In 1945 Czech and Slovak troops surrounded the village and demanded that all ethnic Hungarians leave.
