Short answer
Federal agency is a broad organizational term. A cabinet department, such as the Department of State, is one of the major executive departments headed by a Cabinet member. Agencies can sit inside departments or exist outside the Cabinet structure, so the two labels are not interchangeable. 1 2
A cabinet department is a major kind of executive-branch agency; many federal agencies are not cabinet departments.

The table summarizes the cited definitions and the article’s stated scope. 1 2
What each thing is
Federal agency. A federal government organization authorized to carry out particular functions. 1
Cabinet department. One of the major executive departments whose head serves in the President cabinet. 2
Key differences
The federal directory lists departments alongside other agencies and government bodies. The Cabinet is an advisory and leadership group associated with executive departments and other designated officials; not every agency head is a department secretary. 1 2
How to tell them apart
Check the entity formal name and placement on USAGov or its authorizing law. A named Department is generally a cabinet department; an independent commission or bureau may be an agency without being a department. 1 2
Where they overlap
Departments are themselves federal organizations and contain agencies or offices. Both may issue regulations, administer programs and interact with the public under delegated authority. 1 2
Edge cases
“Agency” can be defined differently in particular federal statutes. Some agencies are within a department, some are independent, and Cabinet attendance can include officials who do not head an executive department. 1 2
Why the distinction exists
The labels clarify where a body sits in the federal structure and who leads it without mistaking all federal offices for Cabinet departments. 1 2
Common misconceptions
EPA is a federal agency but not a Cabinet department. A Cabinet department is not outside the category of federal agency just because it is large. 1 2
Examples
The Department of Agriculture is a Cabinet department; a component service within it is an agency or office but not another Cabinet department. 1 2
