Michael John Murphy is an American diplomat who has served as the United States ambassador to Bosnia and Herzegovina since February 2022.

In Washington, D.C., he served as chief of staff to both the Assistant Secretary of State for European and Eurasian Affairs and the Director General of the Foreign Service.

[9][10] Michael Murphy has been accused of interfering in the formation of the Bosnian government, specifically by actions perceived to undermine the electoral will of the Bosniak (Muslim) population through the suspension of the constitution[11] through the OHR.

The Heritage Foundation, a conservative US think tank, accused Murphy of prioritizing Bosniak interests[15] over those of Croats and Serbs, potentially undermining US foreign policy goals and benefiting Russia.

[16] The Heritage Foundation's letter, which was widely circulated, claimed that Murphy was acting at the behest of the Biden administration and that his actions would benefit Russia and Iran, while harming US-Croatian relations.

The letter also pointed to potential conflicts of interest involving Murphy and members of the Biden administration, citing connections to the Albright Stonebridge Group.
