Ulus is a quarter in Ankara, Turkey and is located at the center of the capital city. It was once the heart of old Ankara. The name means "nation" in Turkish.

It is now a predominately a commercial and tourist area made up of banks, malls, shops, hotels, businesses, restaurants, and many historical sites. The first Turkish Grand National Assembly convened here in 1923 in the parliament building at Ulus Square (Turkish: Ulus Meydanı), which still stands in original. Across from the historical parliament building is the city's oldest hotel, the Ankara Palas, where Ataturk had stayed. Ankara Citadel, another historical attraction, is located immediate east of Ulus.
