Diakovce is an old village and municipality in Šaľa District, in the Nitra Region of southwest Slovakia.

In 1228 a twin-towered Romanesque cathedral, the oldest surviving monument in Slovakia, ever built.

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 Diakovce once more became part of Miklós Horthy's Hungary through the First Vienna Award.

The village has a public library, a gym a swimming pool and a football pitch.
