Yes. And no.

According to the Transportation Security Administration (TSA) website, “self-defense spray” is permitted in checked baggage if it:

• is four ounces (118 ml for our European friends) or less,
• has a safety mechanism to prevent accidental discharge and
• contains 2% or less of tear gas (CS or CN) by mass

And technically, you’re supposed to declare your hazardous materials (as per Federal Hazardous Materials Regulations, 49 CFR, 171-180) to the airline or you could be subject to a civil penalty of up to $50,000.
