Breard v. City of Alexandria, 341 U.S. 622 (1951), was a United States Supreme Court case, which held that door-to-door solicitation could be restricted without violating the Due Process Clause, the First Amendment or the Commerce Clause.

Breard was arrested for violating an ordinance that required him to get permission from the owners of the residences where he was soliciting.

[1] Justice Reed's majority opinion said that the state police power to regulate soliciting does not unreasonably burden or conflict with the due process freedom to engage in legitimate business: "The problem is legislative where there are reasonable bases for legislative action".

In a dissenting opinion, Justice Black held that the decision went against recent doctrine.

Vinson and Douglas wrote another dissenting opinion, calling the ordinance "flat prohibition" and arguing that it discriminated against interstate commerce because it made an exception for local farm products.
