Justin Wayne Tkatchenko, CBE BEM (born 2 June 1972)[2] is an Australian-born Papua New Guinean politician.

After Dame Carol's retirement from politics, Tkatchenko won the constituency in the 2012 elections and entered the national parliament as a member of the Social Democratic Party of Powes Parkop.

Re-elected MP in the 2017 elections, he retained responsibility for the APEC summit, and he was shifted in cabinet to become Minister of Lands and Territorial Planning.

In an interview with the Australian Broadcasting Corporation on 10 May, he described critics of his daughter's video as "primitive animals" and "useless individuals".

This remark caused Opposition Leader Joseph Lelang to call for Tkatchenko to be dismissed from his post as Foreign Minister and have him referred to the Ombudsman Commission for misconduct in office.
