Katselovo (Bulgarian: Кацелово) is a village in northern Bulgaria, administered by the municipality of Dve Mogili and part of Ruse Province. It lies 35 km south of Ruse on the southern edge of the Rusenski Lom Nature Park, and 16 km southeast of Dve Mogili. The village begins on the bank of the Cherni Lom river which joins with the Beli Lom to produce the Rusenski Lom which flows into the River Danube near Ruse, and rises very steeply to a high limestone plateau. The distance from the Bulgarian capital, Sofia, is 241.144 km.

Katselovo is 18 km south of the UNESCO World Heritage Listed monasteries and churches of Ivanovo and is located on edge of the same steep limestone escarpment. The road from the valley floor to the top of the escarpment has many hairpin turns. In former times it was a hive of economic activity but is now mainly a farming community, the textile factory and other industries having closed down due to the economic difficulties during the headlong rush from socialism to a free market economy after the Bulgarian Communist Party was renamed in 1990.

One of the major employers is the cooperative "Hope - Katselovo" (Bulgarian: ПК "Надежда - Кацелово")[1], who grow large quantities of wheat, maize and sunflowers. The credit cooperative "Oral" (Bulgarian: Кредитна кооперация “Орало”) continues to play a large part in the village economy as it has done for over 100 years. Most of the residents have large gardens in which they grow vegetables and many keep a cow, goats, sheep or other livestock along with chickens, geese, ducks and turkeys. The fish ponds near the river are used to rear carp for the table.

In 1980 there were 550 houses, 26 of which were empty. 49 houses had only one occupant and 76 houses had two elderly people in. 106 houses had two young people and 293 houses had three or more people living in them. However the population has shrunk considerably in recent years.

During Ottoman rule, Katselovo was the largest village in the area and the church there was used for marriages and baptisms. The present church was built in 1862. There are three cemeteries, one of which is from the early Ottoman period and hasn't been used for a few hundred years, the present cemetery is not very old and was a replacement for the previous one which is full. The area around Katselovo is rich in history, there are several neolithic mounds. Roman remains, Macedonian, Thracian, Byzantine and Roman imperial coins have been found nearby too.

On 5 September [O.S. 24 August] 1877, there was a major battle of the Russo-Turkish war of 1877–78 at Katselovo. The Ottoman forces commanded by Mehmed Ali Pasha and Sabit Pasha defeated an army of Russian troops commanded by Crown Prince Alexander Alexandrovich, Major-General Alexei Timofeev, and other commanders. After retreating from Katselovo to Gorsko Ablanovo, another battle occurred, which once again ended in an Ottoman victory.

Eventually the area was liberated from Ottoman control which led to the Treaty of Berlin, which in turn was instrumental in creating the Principality of Bulgaria which, in 1908, officially declared independence and formed the Kingdom of Bulgaria after 512 years of Ottoman rule.

There is a library, cultural center and cinema between the school and the church, opposite the Mayor's office / Town (village) Hall. The village has a twice daily bus service to Ruse via Dve Mogili. Fuel, (petrol, diesel and LPG) is supplied at the filling station at the top of the hill and at the cooperative Надежда. The nearest railway station is at Dve Mogili and the nearest functioning airports are at Varna, (150 km) or Henri Coandă International Airport and Aurel Vlaicu International Airport serving Bucharest across the Danube in Romania, (100 km). There is also a British ex-pat community.

Due to the declining population, the village school was closed down in 2007 and the children now travel by bus to attend school in Dve Mogili. There are several shops and restaurants in the village, along with a post office and a bakery which produces fresh bread six days a week. There is also a street / livestock market on Sundays which is well attended, Katselovo claims to breed the finest horses in the area and are justly proud of this.

In 2002, Stoyan Vitanov (Bulgarian: Стоян Витанов) wrote a very interesting book about Katselovo, entitled Village Katselovo (Bulgarian: Село Кацелово), detailing the history of the village. It tells of the village's involvement in the struggle for independence at the end of the 19th century, the forming of the first cooperatives and their subsequent evolution, how the village held several records in former times for its agricultural production and other interesting facts about Katselovo. It also contains some photographs of the village from the recent past but unfortunately for English readers this has only been published in Bulgarian.

The climate is temperate, with cold snowy winters and hot dry summers.
