Pusztavacs is a village in Dabas district, Pest county, Hungary, about 54 km south-east of the capital Budapest.

It is notable for featuring the geographical centre of the country.

To mark that centre, an 11 m high octagonal pyramid was built in 1978 by the plans of the architect József Kerényi.

Some sights include ruins of a 15th-century church and a memorial to the 13 martyrs of Arad.
