A special flight of the Biman Bangladesh Airlines carrying the prime minister and her entourage landed at Dhaka's Hazrat Shahjalal International Airport around 8.15am.
The flight had taken off from Minara International Airport in Marrakesh, where the conference took place, around 3.15pm local time on Wednesday.
Hasina had left Dhaka on Monday to join the 22nd session of the Conference of the Parties (COP22) that was held on Nov 15-16.
Hasina delivered a speech in the conference attended by leaders from 80 countries around the world on Tuesday.
She proposed the creation of a fund to support the water and sanitation goals laid out in the UN Sustainable Development Goal (SDG) platform.
This was the first global conference on climate change since the historic Paris Agreement came into force.
Bangladesh was one of the first countries to ratify the agreement, despite not being a significant contributor to global warming.
It is, however, among those that are at high risk from climate change and has participated in international discussions on climate change alleviation accordingly.
