Tudor Petrov-Popa (born 1963) is a Moldovan-born Romanian politician, arrested in Tiraspol in June 1992 by the Transnistrian separatists.
Petrov-Popa was a Soviet army veteran of the war in Afghanistan who was convicted together with four other men in the so-called Ilașcu Group for acts of terrorism including assassination by the separatist authorities of Transnistria.
On 9 December 1993, the Supreme Court of Transnistria found him guilty of murdering a representative of the State with the aim of spreading terror, unauthorised use and theft of ammunition or explosives, and assault.
All members of the Ilașcu Group are believed to have been tortured, subjected to mock executions, psychotropic substances, and forced to sign confessions.
Petrov-Popa, Ivanţoc and the others of their group were Romanian unionists who campaigned for unification of Romania and Moldova.
