There are several .38 calibers out there which have had revolvers chambered for them. .38 Special and .38 Colt Special are the same thing, so if you have a .38 that is either one of those two the answer is yes. .38 S&W, .38 Short Colt, .38 Long Colt are not interchangeable with the .38 Special, so if you have an older gun that is one of those, the answer is no. If you can't figure it out, check with a reputable gunsmith.
