The threshold of originality is a concept in copyright law that is used to assess whether a particular work can be copyrighted. It is used to distinguish works that are sufficiently original to warrant copyright protection from those that are not. In this context, "originality" refers to "coming from someone as the originator/author" (insofar as it somehow reflects the author's personality), rather than "never having occurred or existed before" (which would amount to the protection of something new, as in patent protection).

Copyright finds its international commonality in the Berne Convention that creates the foundation of several concepts of international copyright law, however the threshold for attracting copyright is not defined. This threshold is up to each jurisdiction to determine. While works that do not meet these thresholds are not eligible for copyright protection, they may still be eligible for protection through other intellectual property laws, such as trademarks or design patents (particularly in the case of logos).
