COVID-19 pandemic is a global public health crisis that claimed lives of millions of people worldwide. Not only health sector, it touches every sector, bringing adverse impacts on livelihood.   Income loss and layoffs due to this pandemic has pushed a huge population under the extreme poverty line. As the COVID-19 situation has severely affected the income and livelihood of the people, this study aimed to find out the livelihood strategies of the lower income class of Bangladesh during Covid-19 crisis and how their livelihood strategies shape their daily life. This study employed a case study design. A sample of 40 households was selected purposively from three districts of Bangladesh, namely Nilphamari, Panchagarh and Chapainawabganj. Qualitative data of this study was collected by conducting semi-structured interviews. Data analysis was framed around the Sustainable Livelihoods Framework. The study revealed that after experiencing income loss, people from the lower income class had undertaken unsustainable livelihood strategy for immediate survival. Those who relied solely on financial capital had mostly experienced negative livelihood outcomes. Lack of motivation, inadequate institutional support and mental stress were some other factors that had brought influence over people’s livelihood choices and ultimately deplete their livelihood and well-being.
