The United States Social Security Administration (SSA) is an independent agency of the U.S. federal government that administers Social Security, a social insurance program consisting of retirement, disability and survivor benefits. To qualify for most of these benefits, most workers pay Social Security taxes on their earnings; the claimant's benefits are based on the wage earner's contributions. Otherwise benefits such as Supplemental Security Income (SSI) are given based on need.

The Social Security Administration was established by a non-positive law codified at 42 U.S.C. § 901 (49 Stat. 635). It was created in 1935 as the "Social Security Board", then assumed its present name in 1946. Its current leader is Kilolo Kijakazi, who serves on an Acting basis.

SSA is headquartered in Woodlawn, Maryland, just to the west of Baltimore, at what is known as Central Office. The agency includes 10 regional offices, 8 processing centers, approximately 1300 field offices, and 37 Teleservice Centers. As of 2018, about 60,000 people were employed by SSA. Headquarters non-supervisory employees of SSA are represented by American Federation of Government Employees Local 1923. Social Security is the largest social welfare program in the United States. For 2014, the net cost of Social Security was $906.4 billion, an amount corresponding to 21% of US Federal Government expenditures. By 2020, it had increased to $1.10 trillion.
