If you've heard the term "single origin," it was probably about coffee. Single origin coffee and single origin chocolate are the same idea: the key ingredient, coffee beans or cacao beans, comes from one place.
"Single plantation" and "single estate" mean cacao from one specific property, so it was sourced from a smaller area. That can, but doesn't always, make the cacao's flavor more distinct, because of its variety, its growing conditions, and a shorter trip to fermentation. In short, single origin chocolate is made with cacao from one origin, or place. How small that place is varies a lot from bar to bar.
Three bars, three levels of origin
All three of these bars are made with cacao from Madagascar. Each one names its origin more precisely than the one before.
Bonnat
Country level: Bonnat names Madagascar on the wrapper. A light roast on Trinitario cacao gives a soft, fruity, smooth 75% bar.
$15.00
Francois Pralus
Region level: Pralus narrows it to the Sambirano Valley, with red currant, yellow fruit, and citrus notes.
$14.00
Ritual Chocolate
Estate level: Ritual's bar comes from the Bejofo estate in the Sambirano Valley, with raspberry, citrus, and peanut notes.

Why "single origin" can mean very little
Historically, an origin is a country, then a city, or even a specific neighborhood. Because of how cacao is processed before it becomes chocolate, very little of the world's cacao can be traced back to an area as small as a neighborhood. Some very small cacao farms do sell to chocolate makers, but that isn't the norm. Most makers use countries as their frame of reference for "single origin."
A maker working with several single origin cacaos will often call their creations their "Nicaragua bar" or their "Vietnam bar." That generalizes the flavor of one cacao and one harvest as the flavor of an entire country. It also makes it easier for large manufacturers to buy the cheapest cacao they can find from different parts of a country and blend it in large batches into a single origin bar. It's still from one country, after all, and single origin chocolate usually sells at a premium.
The term "single origin" says nothing about the quality of the beans or the sugar, and it doesn't guarantee that farmers were paid a fair price. Chocolate made with cacao from a single estate is likely bought directly from a farmer, but even that isn't guaranteed. That's why traceability from the maker matters.
If you're going to pay more, it should be for a better bar overall: better for farmers, and better for your taste buds.

Shop single origin chocolate
Single origin is easiest to understand with a bar in hand. Taste Peru against Madagascar against Vietnam, or try 100% dark chocolate, where no sugar gets between you and the origin.
