Kolindsund (English: Sound of Kolind) is a elongated lakebed on the Djursland peninsula in Denmark. It extends west, inland from the coastal town of Grenå by the Kattegat sea to the railway town of Kolind at its western end. The former lake was drained through a series of canals, dams, and pumping stations beginning in May 1874. Today, the area is rich farmland kept dry by means of electric pumping stations.

== Geography == thumb|Map of the region from the 1820s, when the Kolinsund was still a Lake. The sound was formed by a low glacial valley system and is surrounded by cliffs up to 35 meters high. During the Stone Age, Kolindsund was a saltwater sound that separated the Djursland peninsula from the mainland, creating an island. By the Middle Ages, the entrance of the sound had been blocked off near the town of Grenaa, turning the area into a navigable lake, which likely only had a depth of a few meters. This closure was likely caused by wind-driven sand drifts in combination with sea level changes and/or land elevation changes.
