Kyriakos Amiridis, in Greek Κυριάκος Αμοιρίδης was a Greek career diplomat who served as the Ambassador of Greece to Libya and Brazil. He was reported missing on 28 December 2016 while serving as ambassador to Brazil and his body was found near Rio de Janeiro the next day.

Amiridis began working for the Ministry of Foreign Affairs in Athens in 1985 and was transferred to the Ministry of Macedonia and Thrace in Thessaloniki. His first foreign position was at the Greek Embassy in Belgrade, Serbia from 1988.

In 1993, Amiridis started working in Brussels at the Permanent Representation of Greece to the European Union. He returned to Greece in 1997 to work in the European Foreign Affairs Department at the Foreign Ministry in Athens.

In 2000, Amiridis moved to Brazil to serve as the Consul General at the Honorary Consulate of Greece in Rio de Janeiro. Three years later, he became Consul General at the Consulate General of Greece in Rotterdam, The Netherlands.

In 2004 Amiridis married Françoise de Sousa Oliveira, a Brazilian national, and together they had one daughter.

After returning to Athens in 2008, Amiridis was in 2012 appointed to serve as the Ambassador of Greece to Libya. In 2016 he was chosen to serve as Ambassador to Brazil and he presented his credentials to Brazilian Vice President Michel Temer on 25 May 2016.

Amiridis was reported missing while on vacation in Rio de Janeiro in late December 2016. He was last heard from on the evening of 26 December when he sent a message from his phone. His wife Françoise reported him missing two days later and claimed that she had been unable to contact him.

On 29 December, Brazilian police said a homicide team had launched an investigation into the ambassador's disappearance. Hours later, a body was found in a burnt-out car underneath an overpass of the Arco Metropolitano do Rio de Janeiro highway near Nova Iguaçu. The vehicle had been rented by Amiridis and the remains were positively identified as the ambassador.

On 30 December, Amiridis's wife Françoise and two other people were detained in connection with the ambassador's apparent murder. One of the apprehended figures, military police officer Sergio Moreira, is suspected of having been in an affair with Françoise and confessed to the murder. The roles of the wife and the second man is still unclear. Police believe Amiridis was murdered in an apartment in Nova Iguaçu where the couple and the wife's parents were staying for the Christmas holiday. Blood stains were found on a sofa in the apartment
