Dunajská Lužná (Hungarian: Dénesdtorcsmisérd) is a municipality (village) in the Bratislava Region of western Slovakia in Senec District.

There is a large Roman Catholic community in Dunajská Lužná with the Church, devoted to "The Elevation of the Holy Cross".

The municipality of Dunajská Lužná is also well known in European archaeology for its burial mound which dates from around 700 - 500 BCE.

During the archaeological survey in the "Nové Košariská" part of the municipality, a necropolis with fire-type burials and a central earth-grave was studied.

[5] One of these is Dunajská Lužná's strong[citation needed] Roma population, which is renowned for their skills as blacksmiths,[6] and much of the ironwork seen in and around Bratislava is the craft of these smiths.
