It is usually where the gas enters your house at the meter. It's usually an ordinary little valve, but has just a tab on it which requires a wrench to close it. A crescent wrench will work. However, it is not a bad idea to keep a simple little gas shut off wrench ($5-$10 at most hardware stores) located at the valve. I keep one of those little wrenches zip tied to the pipe by the shut off valve. In the event of an earthquake (our most likely hazard at my house) I can easily break the zip tie and use the wrench to shut off the gas.
