Gomel (Russian: Гомель, IPA: [ˈɡomʲɪlʲ]) or Homyel (Belarusian: Гомель, romanized: Homieĺ, IPA: [ˈɣomʲelʲ]) is a city in south-eastern Belarus. It serves as the administrative centre of Gomel Region and Gomel District, though it is administratively separated from the district. As of 2025, it is the second-largest city in Belarus, with 501,193 inhabitants.

There are at least six narratives of the origin of the city's name. The most plausible is that the name is derived from the name of the stream Homeyuk, which flowed into the river Sozh near the foot of the hill where the first settlement was founded. Names of other Belarusian cities are formed along these lines: for example, Polotsk from the river Palata, and Vitebsk from the river Vitsba.

The first appearance of the name, as "Gomy", dates from 1142. Up to the 16th century, the city was mentioned as Hom', Homye, Homiy, Homey, or Homyi. These forms are tentatively explained as derivatives of unattested *gomŭ of uncertain meaning. The modern name for the city has been in use only since the 16th or 17th century.

Gomel was founded at the end of the 1st millennium AD on the lands of the Eastern Slavic tribal union of Radimichs. It lay on the banks of the Sozh River and the Homeyuk stream. Sozh's high right bank, with bluffs carving through, provided a natural fortification. For some time, Gomel was the capital of the Gomel Principality, before it became part of the Principality of Chernigov. Gomel is first mentioned in the Hypatian Codex under the year 1142 as a territory of the princes of Chernigov. For some time, Gomel was ruled by the prince of Smolensk Rostislav Mstislavich before it was re-captured by Iziaslav III Davidovich, after whose death it belonged to Sviatoslav Olgovich and then to Sviatoslav's son Oleg. Under Oleg, Gomel went to the Principality of Novgorod-Seversk. The next ruler was Igor Svyatoslavich—the protagonist of The Tale of Igor's Campaign. During this period, the town was a fortified point and the centre of a volost. In the 12th–13th centuries, the city's area was no less than 40 ha, and it had developed various crafts and was connected by trading routes with the cities of northern and southern Rus'. Archeological data have shown that the city was badly damaged during the Mongol-Tatar invasion in the first half of the 13th century.

In 1335, the Gomel region was annexed to the Great Duchy of Lithuania by Algirdas. From 1335 to 1406, it was under the ownership of Prince Patricia Narymuntovich and his sons, from 1406 to 1419 the city was ruled by the grand duke's deputies, from 1419 to 1435 it belonged to Prince Svitrigaila, from 1446 to 1452 to Prince Vasiliy Yaroslavich, from 1452 to 1483 to the Mozhaysk prince Ivan Andreyevich, and from 1483 to 1505 to his son Semyon, who transferred it to the Grand Principality of Moscow.

During the Second Muscovite–Lithuanian War of 1500–1503, Lithuania tried to regain Gomel and other lands transferred to Moscow, but had suffered defeat and lost one-third of its territory. In 1535, Lithuanian and Polish forces under Jerzy Radvila, Jan Tarnowski and Andrzej Niemirowicz re-captured the city after the surrender of Moscow's deputy, D. Shchepin-Obolensky. In the same year, the Great Duke of Lithuania Sigismund Kęstutaitis founded Gomel Starostwo. According to the peace agreement of 1537, Gomel together with its volost remained a Lithuanian possession. In 1535–1565, Gomel was the centre of the starostwo, and from 1565 onwards it was in Rechytsa Powiat of Minsk Voivodeship.

In 1560, the city's first coat of arms was introduced. In 1569, Gomel became part of the Polish–Lithuanian Commonwealth. From this moment on, the city became the arena of numerous attacks and battles between the Cossacks, Russia, and the Polish-Lithuania Commonwealth. In 1572, Gomel Starostwo was given to B. Sapega. At the beginning of the 1570s, Gomel was captured by the forces of Ivan the Terrible, but in 1576 it was re-captured by J. Radvila. In 1581, Gomel was again attacked by Russian troops, and in 1595–1596 it was in the hands of Severyn Nalyvaiko's Cossacks.

After the beginning of the struggle against Orthodox Christianity in Lithuania, Orthodox Nikolayevskiy Cathedral was closed, following the order of Greek Catholic Eparch Josaphat Kuntsevych in 1621. In 1633, the city was besieged by Cossacks Bulgakov and Yermolin, in 1648 captured by Golovatskiy's Cossack detachment, and in 1649 by Martyn Nebaba's detachment. After that, Gomel got through several sieges in 1651 but in 1654 was captured by Ivan Zolotarenko's detachment. He and his sons held the city until 1667 and then began to serve under Alexis of Russia, however, after the Truce of Andrusovo Gomel at last returned to the Polish–Lithuanian Commonwealth, where it first belonged to M. K. Radvila and then—till the annexation by the Russian Empire—to the Czartoryski family. During the Great Northern War, Russian forces under Aleksandr Danilovich Menshikov stood in Gomel. In 1670, Gomel received Magdeburg rights. Towards the middle of the 17th century, the city fell into crisis mainly due to the struggles mentioned above. It suffered significant damage, the population decreased severely, and many crafts disappeared.
