I called the Crock Pot manufacturer today to ask them this question and they said China. If you go to the Crock Pot website you can find the manufacturer's information but you have to call to ask where they make the Crock Pot.The same company (Jenson) also owns Sunbeam and a bunch of other brands.
In my opinion, if an item doesn't say where it's made, it's made in China. When a company makes something in the USA, it's something to put all over the package, because they know consumers will snap it up. With other countries, there's usually a place stating where it's made, such as Thailand, India, France, Japan, the UK, etc.
