Lam took her oath before Chinese President Xi Jinping, who oversaw the swearing-in ceremony along with the rest of her cabinet. She is Hong Kong's first female leader, reports Xinhua news agency.
"It is with a humble heart that I accept this greatest honour of my life and prepare to take on the greatest challenge in my public service career," Lam said in her inauguration speech.
Lam said she will "resolutely do everything" within her ability to implement the "one country, two systems" principle, uphold the Basic Law of the HKSAR and defend the rule of law.
"As we capitalise on our strengths and harness the opportunities presented by our country's development, Hong Kong's future is indeed bright and promising," Lam added.
