The 61-year-old man had also suffered from "chronic illnesses," said Qatar's Supreme Council of Health in a statement published by the official QNA news agency.
Another foreign man, aged 48, who had contracted the virus, was discharged from a Qatar hospital after being successfully treated for three weeks, the same statement said.
Neither of the two men were identified.
In September, Qatar announced two other deaths from MERS of a man and a woman.
Experts are struggling to understand the disease, for which there is no vaccine.
It is considered a deadlier but less-transmissible cousin of the SARS virus that erupted in Asia in 2003 and infected 8,273 people, nine percent of whom died.
Like SARS, MERS appears to cause a lung infection, with patients suffering from a temperature, coughing and breathing difficulties.
But it differs in that it also causes rapid kidney failure, and the extremely high death rate has caused serious concern.
And the Saudi government said on November 11 that a camel in the kingdom has tested positive for MERS, the first case of an animal infected with the coronavirus.
