Yes, there are a few species of "Freshwater Barracuda" that you can keep in aquariums. They're not actually related to marine barracudas, but look similar. They grow to about a foot long, a 125 gallon aquarium or bigger can house them for life.
They are very neat fish, very fast and cool predators to watch. They are skiddish and will literally break their noses from getting scared and running into the side of the aquarium, this is quite common if you try to keep them in a relatively small aquarium.
Acestrorhynchus falcatus, "Red Tailed Barracudas" are the most common ones you'll see. They don't usually grow larger than 10-11".
Acestrorhynchus falcirostris, "Yellow Tailed Barracudas" are similar, but more elongated and slender. They typically grow to more about 13-14".
There are also Ctenolucius hujeta or "Riocket Gars", which have a longer mouth more like a gar. They get bigger than the other barracudas, but not usually more than 16" or so in aquariums.
I think Red Tail Barracudas are generally the easiest to keep. There are several places online that carry them, but they're often out of stock. Expect to pay about $25-30+ for them. They are illegal in some states. You can find more information and pictures if you google search the common or scientific name.
