Čierny Brod (Hungarian: Vízkelet) is a village and municipality in Galanta District of the Trnava Region of south-west Slovakia.

The municipality lies at an elevation of 120 metres and covers an area of 17.699 km². It has a population of about 1559 people.

The territory was already a part of the Kingdom of Great Moravia, the first Slavic state ever, when, after weakening battles with the Frankish Empire, in the 9th century, the eastern part of Great Moravia was occupied by nomadic Magyar tribes. The territory of the village became part of the Kingdom of Hungary, later acknowledged by the Frankish Empire. In historical records the village was first mentioned in 1223. Before the establishment of independent Czechoslovakia in 1918, it was part of Pozsony County. After the Austro-Hungarian army disintegrated in November 1918, Czechoslovak troops occupied the area, later acknowledged internationally by the Treaty of Trianon. Between 1938 and 1945 Čierny Brod once more became part of Miklós Horthy's Hungary through the First Vienna Award. From 1945 until the Velvet Divorce, it was part of Czechoslovakia. Since then it has been part of Slovakia.
