Short answer
A federal statute comes from Congress’s lawmaking process. A federal regulation is an agency rule issued under legal authority, often through a process that includes public notice and comments. Both can be binding, but they come from different institutions and are made differently. 1 2
A regulation operates under authority supplied by law; a statute is enacted by the legislature.

What each thing is
Statute. A law enacted through the legislative process by Congress in this federal scope. 1
Regulation. A rule issued by a federal agency under legal authority, commonly through rulemaking. 2
Key differences
The everyday word “law” can include both, which makes authorship the useful distinction. Congress can prescribe duties directly or delegate implementation details to an agency. The agency may then issue regulations within its authority; those regulations cannot lawfully override governing statutes. 1 2
How to tell them apart
Trace the citation and issuer. A section of the United States Code usually reflects statutory law; a section of the Code of Federal Regulations reflects agency rules. Those compilations are clues, but verify the legal text and history for a particular question. 1 2
Where they overlap
Statutes and regulations may govern the same subject and work together. A regulated business may need to follow both the broad statutory requirement and detailed implementing rule. 1 2
Edge cases
Congress can write highly detailed statutes, and agencies may issue guidance that is not itself a binding regulation. Courts can invalidate statutes or regulations on legal grounds. State governments have their own legislative and administrative structures. 1 2
Why the distinction exists
Legislatures set legal frameworks while agencies administer and implement them within delegated bounds. Separate terms clarify democratic enactment versus administrative rulemaking. 1 2
Common misconceptions
A regulation is not automatically “just a suggestion.” A valid regulation can carry legal force; conversely, an agency cannot create any rule it wishes without authority. 1 2
Examples
Congress enacts a statute authorizing a safety program. An agency conducts rulemaking and issues a regulation specifying technical compliance requirements under that authority. 1 2
