Dietlikon is a municipality in the district of Bülach in the canton of Zürich in Switzerland, and belongs to the Glatt Valley (German: Glattal).

Dietlikon is first mentioned in 1124 as Dietlinchoven.For a long time, the municipality at the foot of the Hardwald forest led a rather sleepy existence.

The clan leader Dietilo, perhaps also called Dietelo or Dieto ("son of the people"), may have been persuaded to settle in the area of today's old part of the village by the presence of water.

Of the rest of the land, 44.1% is settled (buildings or roads) and the remainder (1.2%) is non-productive (rivers, glaciers or mountains).
