31 Totally Accurate Mark Twain Quotes (And Where to Find Them)

Everyone loves good Mark Twain quotes, right? Samuel Clemens (the man who wrote under the pseudonym Mark Twain) embodied snark before it was a thing, and he was prolific, so there are quotes from him about everything.

Before we get to the funny stuff, a note about accuracy:

There’s something you should know about Mark Twain: he’s misquoted. A lot.

I live in Connecticut, the home of the Mark Twain House, so I thought they might be a good source of accurate Twain quotes. The Twain House, as it turns out, recommends Twain Quotes, a database of attributed quotes by and about Mark Twain. The site was put together by Twain scholar Barbara Schmidt, and it’s one of the few sources of reliable Twain quotes. Schmidt has organized the quotes by subject, and there’s a citation for every single quote. She’s also included Twain’s newspaper articles and links to other resources. Everything on the site is the real deal.

If you’re looking for reliable Mark Twain quotes in book form, Schmidt recommends The Quotable Mark Twain, by R. Kent Rasmussen.

You can also get accurate quotes from the Twain House itself (although the site directs you to Schmidt’s database).

A lot of these Mark Twain quotes are funny, some are so sarcastic you might need to read them twice, and some are even very sad. Most are insightful.

Here’s another thing you should know about Twain: he was a progressive.  He (eventually) supported women’s suffrage and was outspoken against racism…but what was progressive in the late 1800s can look pretty problematic now. I included a few of his progressive quotes, but if you want to see all of them, check out the quote database I mentioned above.
