It depends, on which criteria we are seeking the most underrated country,

Tourism

• Asia

Bhutan

The most underrated country I feel is Bhutan. A country lying in the trench of Himalayas, the peaceful and full of panoramic view, the Bhutan is considered as one of the happiest nation in the world,

Isolated from the whole world, the country established an embassy in India & Bangladesh only.

Isolated from the mainland, a group of island is the destination you would fall in love with, a heaven for the tourist and one of the best places on this planet with its own type of luxury beaches.

Development

• Eurasia

Azerbaijan

The country with the largest KFC, yes the capital Baku is known for its largest KFC with the capacity to host 300 guests at a time, is developed enough to host people in an urban environment.

• Africa

Angola

We imagined Africa as the zone dwelling in poverty, but we have yet not seen the urban part of Africa, Luanda is more like a western city in the mid of South West Africa

There are a lot more places on the earth still waiting to host the global crowd, but due to stereotyping people struggling with their decision to visit.
