Federal Home Loan Mortgage Corporation is a private corporation chartered by the United States government to increase funds for housing. It is commonly referred to as Freddie Mac.

Freddie Mac buys home mortgage loans from such institutions as banks, savings and loan associations, and mortgage companies. Freddie Mac combines the loans into large pools and sells interests in the pools to investors. The investors receive principal and interest from the homeowners' mortgage payments on the loans purchased by Freddie Mac. Among the investors are pension funds, insurance companies, and bank trust funds. The corporation uses the funds from investors to buy more mortgage loans from lenders.

Congress created Freddie Mac in 1970. The corporation receives no direct financial support from the U.S. government. It has an 18-member board of directors. Its headquarters are in Reston, Va.
