Incomplete question. However, I assumed you are referring to Oceania mentioned in the novel, "Nineteen Eighty-Four" by George Orwell.
Answer:
the Ministry of Plenty
Explanation:
Interestingly in Nineteen Eighty-Four among all the other ministries highlighted in the novel, the "Ministry of Plenty" is responsible for the rationing of food that citizens of Oceania receive.
So we could say that the 'Ministry of Plenty' acts as a direct opposite to the normally expected meaning of its name.
