Vijaya Kumar Rajah SC (born 14 January 1957)[1] is a Singaporean lawyer who served as the eighth attorney-general of Singapore between 2014 and 2017.

One of the cases presided by Rajah as a High Court judge was the 2006 case of Constance Chee Cheong Hin, a schizophrenic who was charged with throwing a girl off her HDB block and causing the death of four-year-old Sindee Neo.

He was also the chair of a committee that produced an influential report in 2007 reviewing Singapore's legal sector.

Prime Minister Lee Hsien Loong thanked him for carrying out his duties "with dynamism and commitment".
