Final answer:
The Kurds are the stateless nation that mainly resides in Turkey, Iraq, and Iran. Despite having significant populations in these countries, they lack a recognized independent nation of their own, making them 'stateless'.
Step-by-step explanation:
The group known as a stateless nation and largely residing in Turkey, Iraq, and Iran is the Kurds. This group of people does not have any recognized autonomous state or country recognized by the international community. Instead, they inhabit regions across several countries, including Turkey, Iran, Iraq, and even Syria. The term 'stateless' refers to their lack of recognition as a separate nation or country by these countries and the international community.
The Kurds have had a long history in the Middle East, with roots going back to the Ottoman Empire times. They have found themselves caught in geopolitical turbulent situations multiple times that have kept them from forming an independent Kurdistan, thus becoming a stateless nation.
