Kostopil (Ukrainian: Костопіль, Polish: Kostopol) is a town, originally named Ostlec Wielki or Ostaltsi, on the Zamchysko river in Rivne Oblast of western Ukraine. It is the administrative center of the Kostopil Raion. Population: 30,467 (2001).

Kostopil was the property of Prince Władysław Dominik Zasławski and is mentioned in 1648-58 registers. It was originally a village based on a local iron mine, but in 1792 the local landowner, Leonard Wortzel, obtained town privileges for his estate including the right for an annual fair from Stanisław August Poniatowski, the last King of the Polish-Lithuanian Commonwealth. At this time Wortzel changed the town's name to Kostopol.

During the Partitions of Poland many Germans migrated from occupied Polish lands to Volhynia because repossessed land was available there for purchase. The region between Anielowka and Kostopol contained many German villages. Settlement in the town was encouraged by the imperial authorities but it stagnated until a railway station was opened on the Rovno - Vilna line in the late 1890s. The railway promoted the establishment of new industries such as flour mills, oil pressing, spinning mill, sawmill, and a match factory. Development was interrupted in 1906 when a fire destroyed most of the town's buildings. Afterwards, most new construction used bricks.

The town had become a centre for Jewish settlement in the interwar Poland and this continued until World War II, when about 40% (about 4,000) of the population were Jewish. Kostopol became the local administrative centre of Kostopol County in 1925. The town had been joined with Poland after the end of First World War. By the end of the 1920s, there were three timber yards (two of them Jewish owned, one government owned), three plywood factories (Jewish owned), two furniture factories, two glass factories, two agriculture machinery works, three flour mills (two Jewish owned), two oil presses, four tar and turpentine factories and a brick factory operating in Kostopol. In nearby Janowa Dolina, there were granite and basalt quarries, with railway links to Kostopol station. The Polish government built a housing projects for the quarry workers.
