The former federal prosecutor said, with the mandate for change, she will work to make the city’s streets safe again.
She said she will work to give the city’s children access to the high-quality education they deserve.
She added the city can build trust between the city’s residents and “its brave police”.
Ms Lightfoot and Ms Preckwinkle were the top two in the February general election that saw 14 vie to succeed mayor Rahm Emanuel, a former White House chief of staff to Barack Obama.
He decided against running for a third term.
Ms Lightfoot will be sworn in on May 20
