Alattyán is a village in Jász-Nagykun-Szolnok county, in the Northern Great Plain region of central Hungary.

Its first written mention dates back to 1212 AD in the Váradi regestrum, in which it appears as Olaptiuã.

It survived the Turkish invasion, but the wars of liberation also caused great destruction in Alattyán.

On 15 May 2007, The New York Times published an article about looking for the ancestral estate of French president Nicolas Sarkozy's family in Alattyán.

[1] Nowadays, for the elder inhabitants of Alattyán, Nicolas Sarkozy, nagybócsai Sárközy Miklós in Hungarian, is still considered their lord.
