No work of Marx’s contains this line. Wikiquote lists it among his misattributed quotations ↗, and the only appearance it cites is a 2003 humour book, W. C.

No documented source
There is no fuller context to give: the line has no documented original setting. It circulates as a free-floating one-liner, and the earliest appearance anyone has cited for it is a 2003 book of bathroom humour that already presents it as a Marx quotation.
Wikiquote’s Karl Marx page ↗ places this exact sentence in its Misattributed section, with the note that it was “attributed to Marx (possibly in jest)” in W. C. Privy’s Original Bathroom Companion (2003).
That book is real and datable: Open Library’s catalogue record ↗ gives W. C. Privy’s Original Bathroom Companion by Erin Barrett and Jack Mingo, St. Martin’s Griffin, New York, 2003, 478 pages — a compilation of jokes and trivia, not a source on Marx.
Quote Investigator has not investigated the joke itself: a search of QI for the phrase ↗ returns nothing, so no earlier author has been traced. Meanwhile quote aggregators such as AZQuotes ↗ carry it under Marx’s name with no citation of any kind.
No rights status can honestly be asserted, because the wording has no identified author or first publication. The earliest appearance cited by Wikiquote is W. C. Privy’s Original Bathroom Companion (St. Martin’s Griffin, 2003), which is itself in copyright, but that book is a compilation and there is no evidence it originated the line. Treat the quotation as of unknown provenance rather than public domain.

Fact-check
Why this one sticks to Marx
The joke is a capitalist punchline wearing a communist’s name. It sounds like Marx because it says out loud what he spent three volumes arguing — that profit depends on someone else’s dependence — and that resemblance has been enough to keep it circulating under his name for over two decades.
A second wording — “Sell a man a fish, he eats for a day, teach a man how to fish, you ruin a wonderful business opportunity” — circulates on Goodreads under Marx’s name ↗ with no book or source given. The site itself notes that quotations there are community-added and unverified.

The proverb being parodiedLao-Tzu, Maimonides, or “an old Chinese proverb” Also unsourced
The straight version has its own attribution problem. Quote Investigator ↗ traces newspaper claims calling it Chinese, Italian, Navajo and Lao-Tzu’s, and finds the earliest fishing-form wording in an 1885 English novel instead.
Marx did write a famous sentence about fishing, and it is the opposite of this one in spirit. In The German Ideology, drafted with Engels in 1845–46 but not published until 1932, he imagines a society in which nobody is trapped in a single trade: it “makes it possible for me to do one thing today and another tomorrow, to hunt in the morning, fish in the afternoon ↗, rear cattle in the evening, criticise after dinner.” Fishing there is freedom, not a revenue stream.
The fake quotation works as a joke because it compresses a real Marxian argument into a boardroom voice — and that compression is exactly what makes it modern. The vocabulary of “a wonderful business opportunity” belongs to the age of the management aphorism, not to a nineteenth-century Prussian in the British Museum Reading Room.
Fishing, for Marx, was what you did in the afternoon because you were free — not what you sold someone in the morning.
The chronology, and what Wikiquote does not claim
The chronology is the cleanest disproof available. Quote Investigator’s survey finds the earliest fishing version of the proverb in Anne Isabella Thackeray Ritchie’s Mrs. Dymond (1885): “if you give a man a fish he is hungry again in an hour. If you teach him to catch a fish you do him a good turn.” Marx died on 14 March 1883. A parody cannot precede the thing it parodies.
It is worth being precise about what Wikiquote does and does not claim. It does not say the 2003 humour book invented the line — only that this is where the attribution to Marx has been located in print. The joke may well be older in spoken or online circulation; no researcher has published an earlier trace of it.

1818–1883 · German philosopher, political theorist & revolutionary socialist
Karl Marx was a German philosopher, social and political theorist and revolutionary socialist, born in Trier in 1818 and buried in London in 1883. His major works — The Communist Manifesto (1848, with Friedrich Engels) and Das Kapital (volume I, 1867) — analysed capitalism as a system that extracts surplus value from labour. He is a magnet for invented quotations precisely because so many modern one-liners about money sound vaguely like something he might have said.
