Nacina Ves (Hungarian: Nátafalva) is a village and municipality in Michalovce District in the Košice Region of eastern Slovakia.

In historical records the village was first mentioned in 1219. The Hungarian State Archives record that the village was granted by King Bela IV to his son Nata and the name became Natafalva. (Village of Nata) The Natafalusi family were the nobles who controlled the town for hundreds of years, many of them moving after the Kuruc Wars in the early 18th century. In the late 19th century, records indicate that this was a "toth falu" (Slovak village) with a majority Slovak population, but with a sizeable Hungarian minority. After Hungary was partitioned in 1920, Natafalva found itself in the newly created Czechoslovakia. Many Hungarian residents of the town left, immigrating to North America or back to what was left of Hungary. The name was changed from Natafalva to Nacina Ves and during World War II, remaining Hungarians who did not swear that they were Slovaks were expelled.

The village lies at an altitude of 125 metres and covers an area of 15.803 km. The municipality has a population of about 1750 people.

The village has three bus stops with bus shelters. Regular bus routes available include to Michalovce, Strážske, Humenné and Vranov nad Topľou.

Nacina Ves also has its own small railway station, located west of the village, next to the local railway line between Michalovce and Humenné (part of the ŽSR regional line no. 191 between Michaľany and Lupków).
