Zlatopil (Ukrainian: Златопіль), formerly known as Pervomaiskyi until 2024 and Likhachevo or Lykhacheve until 1952, is a city in Lozova Raion, Kharkiv Oblast, Ukraine. It is the fourth largest city in the oblast. Zlatopil hosts the administration of Pervomaiskyi urban hromada, one of the hromadas of Ukraine. Population: 28,510 (2022 estimate).

The city is known for Khimprom, one of the biggest chemical factories in the former Soviet Union. The city has lush green plots and parks, a cultural center named "DK Khimik" and a stadium also named "Khimik".

In 1869 a railway was opened, Kursk-Kharkov-Sevastopol at the current location of the modern city. In August of the same year a whistle stop was built 80 kilometres from Kharkov. Trains stopped for water and firewood and the station was named at first named Oleksiivka and later Likhachevo. Likhachov was a landowner-officer sent there by Empress Catherine II. Likhachov estate was near the village Sivash a few kilometres from the railway. Water was supplied from lake Sivash and a water-tower was built.

After the Russian Civil War the (joint) Alekseevskogo, Berekskogo, Upper Bishkinskogo rural Soviets decided to relocate the peasants of these villages to the farm Likhachevo. So in 1924 a settlement was built in Likhachevo which originally was under the jurisdiction of the Upper Bishkinskyi village council. The founders of the village were migrants from the villages of Alexeevka, Bereka, Maslivka, and Upper-Bishkin. They built streets, such as 1 May Street. Agriculture and crafts schools were built, along with a primary school, which both children and adults attended.

In 1927 the village had 13 lots and 56 residents. In 1928, it was already 85 lots. The population increased as workers came to work at the brick and mechanical plant, as well as the mill. In September 1929, on the initiative of activists Tolokneeva and Fedoseenko, a gang was organized in the village. At the suggestion of porters, it was called "May 1" in honor of the international proletarian holiday. In early December 1929 Lihachevsky machine-tractor station was organized (one of the first in the Kharkiv district). Lihachevsky MTS first served 30 collective Alexeevski district.

A local newspaper Znamiya Truda has been published here since October 1930.

According to the Soviet census of 1939, 640 people lived in Likhachevo.

On 20 October 1941 Axis troops occupied Likhachevo. 38 boys and girls were sent to work as slave laborers in Germany. 15 people from the village joined the partisans in Alexeevski district, whose leaders were Secretary of the Communist Party VS Ulyanov and executive committee chairman AG Buznyka.

Likhachevo repeatedly became the site of fierce fighting. During the war, it changed hands four times. On 16 September 1943 troops of the Steppe Front finally returned Likhachevo to Soviet control.

In 1946 a midwifery unit began to operate in the town. In 1948 a hospital was built, employing two doctors and three nurses.

In 1947 a kindergarten was built.

On 25 December 1948 Likhachevo became the center of the Council of Agriculture, who controlled the farm Pervomajskij, Our Way.

In 1950 a high school was built; its enrollment was 824 students and it employed 28 teachers.

On 24 June 1952 the settlement Likhachevo was renamed Pervomaiskyi.

In 1974 it was an urban-type settlement with several factories and 19400 people.

In 1991 Pervomaiskyi received the status of a city.

Until 18 July 2020, Pervomaiskyi was incorporated as a city of oblast significance and served as the administrative center of Pervomaiskyi Raion though it did not belong to the raion. In July 2020, as part of the administrative reform of Ukraine, which reduced the number of raions of Kharkiv Oblast to seven, the city of Pervomaiskyi was merged into Lozova Raion.

In 2022 attempts were made twice to rename the city as part of the decommunization derussification campaigns in Ukraine. Local residents chose a new name for this city - Dobrodar. But local city deputies twice did not support the renaming at city council sessions. A third attempt late September 2023 was also unsuccessful with one vote lacking for the quorum. After another failed vote in the local city council on 25 January 2024 the Verkhovna Rada (Ukraine's national parliament) can decide on the new name of Pervomaiskyi since the Ukrainian derussification law stipulates that the local city council had until 27 January 2024 to rename the itself and after that date the Verkhovna Rada would do it.

On April 3, the Committee on the Organization of State Power, Local Self-government, Regional Development, and Urban Planning [uk] in the Verkhovna Rada stated their support for renaming the city to Zlatopil. On 19 September 2024, the Verkhovna Rada voted to rename Pervomaiskyi to Zlatopil.

Zlatopil is situated on the Pivdenna Zaliznytsia railway line. The railway station here is called "Likhachove," or, in Russian, "Likhachevo". Zlatopil is also a main road hub which links many other cities like Lozova, Merefa, Balakliia and Izium together with the Kharkiv Oblast.

Zlatopil was planned as a colony for the workers and clerical staff of the Khimprom chemical factory. Until the fall of the USSR in 1992, the city's inhabitants had good earnings, but afterwards, the city's economy collapsed. Many became jobless. However in the late 1990s some private companies moved into Zlatopil.
