Lokman Singh Karki (Nepali: लोकमान सिंह कार्कीListenⓘ, born April 5, 1956), is the former Chief Commissioner of Commission for Investigation of Abuse of Authority (CIAA) of Nepal.

[2] In a landmark verdict, the Supreme Court on 8 January 2017 held that Mr. Karki was not qualified for the appointment to the office of the chief of the Commission for Investigation of Abuse of Authority.

After the impeachment motion was moved, the Republic and Kantipur media groups alleged that Indian Ambassador Ranjit Rae had lobbied to save Karki.

Numerous articles published in Nepalese media also cite instances of power misuse by Lok Man that clearly benefited India in matters of dispute with Nepal.

[8] [9] Karki was controversially appointed as the Chief Commissioner of CIAA on May 8, 2013, by President Rambaran Yadav on the recommendation of the Constitutional Council for a term of six years.

On 27 July 2016, the party protested against the chief of CIAA who did not appear at the meeting of Good Governance and Monitoring Committee (GGMC) of the Parliament held at Singha Durbar citing health problems.

Manmohan Memorial Institute of Health Sciences, where majority of the shareholders are CPN-UML members, the CIAA had written to the Tribhuvan University asking it to make arrangements for granting affiliation to it.

Dr KC accused Karki of protecting corrupt people in medical education sector and breaching his jurisdiction to interfere into Kathmandu University.
