This is the third time she takes over as the premier in the last two decades since Bangladesh returned to democracy from military rule.
She is seeking to reward all parties who joined the January 5 polls, braving a boycott by the BNP-led opposition alliance.
Hasina's party, Awami League, clinched a landslide victory in the parliamentary election, bagging 231 seats in the face of a boycott of the polls by the BNP-led 18-party opposition alliance.
At least 21 people were killed in poll-related violence during the “one-sided” elections. Most voters had preferred to stay home during the January 5 polls in 147 out of 300 constituencies in 59 districts.
Awami League won 231 seats, of which 127 seats were uncontested, giving it a clear three-fourths majority in the country's 10th parliament.
The 18-party alliance led by former premier Khaleda Zia's Bangladesh Nationalist Party (BNP) boycotted the polls after her arch-rival Hasina rejected the opposition's demand for a neutral caretaker regime for election oversight.
