Quick Answer
Yes, quotes can be copyrighted, but only if they are long enough and original enough to count as protected expression. Single famous lines like "I have a dream" are part of a longer protected speech and the speech itself is copyrighted, but a short phrase or slogan is generally not protectable under US copyright law on its own.
The US Copyright Office is explicit on this in Circular 33: short phrases, titles and slogans cannot be registered. Longer quotations, paragraphs and whole speeches usually can.
What Copyright Actually Protects
US copyright protects original works of authorship fixed in a tangible medium. The threshold for originality is low, but it is not zero. The Copyright Office and the courts have repeatedly held that short phrases, names, titles and slogans lack the minimum creative spark and cannot be registered. That is why you cannot copyright "Just do it" or "Where's the beef?" The brand owners protect those through trademark, not copyright.
When a Quote Is Long Enough
There is no fixed word count, but the longer and more distinctive the wording, the more likely it is protected. A full paragraph from a novel, an extract from a song lyric, a passage from a speech, all of that is protected by copyright as part of the larger work. A single tweet might or might not be, depending on whether the wording is creative enough.
Courts have treated 22-word excerpts as protectable in some cases. The Authors Guild v Google case famously turned on the cumulative use of small snippets across millions of books. Quantity matters; so does whether the borrowed bit is the "heart" of the original.
Fair Use, the Big Exception
Even when a quote is copyrighted, US fair use under 17 USC section 107 lets you use parts of it without permission for purposes like criticism, comment, news reporting, teaching and research. Courts weigh four factors: the purpose and character of the use, the nature of the original work, the amount used, and the effect on the market.
Most everyday quoting (a sentence from a review, a paragraph from a politician's speech, a line from a book quoted in your article) falls within fair use as long as you credit the source and do not lift more than you need.
Famous Quotes in the Public Domain
Quotes from authors who died long enough ago, or from works whose copyright has expired, are in the public domain. Shakespeare, the King James Bible, Mark Twain, Jane Austen: quote freely. US works published before 1929 are now in the public domain, with the line moving forward by one year every January.
Be careful with translations and modern editions, which can have their own fresh copyright on the editor's or translator's work even when the underlying text is old.
Quotes on Social Media
Tweets, Instagram captions and TikTok video transcripts are copyrighted by their authors the moment they are posted. Reposting a screenshot of someone's caption is technically a copyright issue, but in practice, the platforms encourage sharing and most authors do not enforce. The risk rises when you use the quote commercially (printed on merchandise, in an ad, on a book cover).
Practical Rules for Writers
- Quote sparingly. Lift the minimum you need to make your point.
- Always credit the source. Credit is not a substitute for permission, but it lowers the temperature in any dispute.
- Watch out for songs and poems. They are short, so even a few lines can be a big proportion. Music publishers are famously protective. Get permission for anything in print.
- Get permission for commercial use. A motivational quote on a mug or T shirt is the riskiest use of all because it is purely commercial and offers no commentary.
Bottom Line
Short phrases and slogans cannot be copyrighted. Longer quotes are protected as part of the larger original work. You can usually quote sparingly under fair use, especially for criticism, news or education, but commercial use of a substantial quote needs permission.
More context worth knowing
To round out the answer, here is some additional background on whether a short quotation qualifies for copyright protection. Style guides treat this rule as more than a cosmetic choice. It signals to readers that the writer respects the original source, follows a consistent convention, and understands the difference between American and British practice. When you write about quotes copyrighted in any professional setting, that consistency is what separates a polished page from a draft that distracts the reader.
Editors at major publishers, including university presses, trade magazines, and legal journals, run every manuscript through a style check that flags exactly this kind of issue. If the guidance feels picky, remember that search engines and screen readers also rely on consistent punctuation to parse a sentence correctly. A misplaced quotation mark can change how an excerpt is rendered in a featured snippet, an email preview, or an accessibility tool.
Practical tip: keep a one-page cheat sheet next to your keyboard with the three rules you reach for most often. For quotes copyrighted, that usually means the rule about capitalization, the rule about punctuation placement, and the rule about block quotations. Anything more than three rules tends to be forgotten under deadline pressure, so curate ruthlessly.
If you write for a global audience, double check whether your house style follows American English or British English. The two traditions disagree on punctuation placement around quotation marks, on the choice between single and double marks for the outer quotation, and on whether long quotations should be indented or set off with a colon. Picking one tradition and sticking to it across a whole site is more important than picking the "correct" one, because mixed styles confuse readers and weaken trust.
Finally, if you are publishing online, remember that screen readers announce quotation marks differently depending on the user's settings. Curly smart quotes, straight typewriter quotes, and the special primes used for measurements are not interchangeable. Use the correct character for the job so that assistive tech reads your sentence the way you intended, and so that copy-paste into another document preserves your meaning.
