Ditrău (Romanian: [diˈtrəw]; Hungarian: Ditró or Gyergyóditró [ˈ(ɟɛrɟoː)ditroː]) is a commune in Harghita County, Transylvania, Romania.

The villages belonged first to the Székely seat of Gyergyószék, which was subsequently absorbed into Csíkszék, until the administrative reform of Transylvania in 1876, when they fell within the Csík County in the Kingdom of Hungary.

[citation needed] After the Hungarian–Romanian War of 1919 and Treaty of Trianon of 1920, the villages became part of the Kingdom of Romania and fell within plasa Gheorgheni of Ciuc County during the interwar period.

[citation needed] From January to March 2020, a xenophobic incident occurred between the local Székely population and two Sri Lankan immigrants who worked at the bakery Ditrói Pékség.

Ditrău is crossed south to north by national road DN12 [ro] (part of European route E578), which runs from Chichiș, Covasna County to Toplița.
