Nope. Well, mostly, but there are a few regions where the tradition is still going. Mauritania only banned slavery in like 2003, and the law is basically a joke. Foreign journalists will tell stories about visiting and being served by rough people dressed in rags, until the host notices them staring and gets nervous.

The gulf states are also famous for having slaves, although in that case it has more to do with cost savings and a lack of scruples, and I don't think they would call them slaves, just workers-who-have-to-work-and-can't-leave. There's various forms of forced labour in probably most places too, but it's a matter of definition if prison labour or indentured labour count as slavery (which is usually what they're counting when they put out figures with a giant number of modern slaves).
