Loosen back tire, pull back on wheel & tighten with chain on sprocket.

1. Adjust the sprocket location to tighten the chain.
2. Make sure that the sprocket is rust-free (you can spray WD40 for that).
3. Have the chain adjusted be removing one link.
4. Sharpen the teeth of the sprocket or get a new one.
5. Check the alignments of the rear sprocket and the pedal section.
6. Change the spring coil for the chain tensor.
Or you can buy a new chain (get the stainless one) and have it installed by a competent bike repairman who will likewise check everything--from wheel alignments, tension control, teeth edges and speed adjustments.

Do NOT loosen and move your back wheel like the others are saying. This will probably make it so your brakes will not work. You need to have your derailleurs adjusted. They control the movement of your chain,. If they are off in one direction or the other they will move the chain right off the gears. Take your bike into the shop and get a tune up. They will be able to fix it in less than an hour.

a few possibilities:
If the sprocket is worn, you need to replace it
The crank may be loose, causing the sprocket to wobble. You need a special tool to tighten it.
The derailleur might not be lined up with the sprocket. You adjust it with a screwdriver. If it is stiff due to oil gunk and sand, you need to soak it in kerosene and re-oil it. If it is working right, it should keep the chain tight enough to stay on.
If none of the above makes sense to you, go to a bike shop.

Loosen the nut & bolt that holds the rear wheel in place, move the rear wheel back a bit, and retighten the nut & bolt. Not too tight, you'll need a little slack in the chain to make sure it rotates properly. You might want to check the wear on the chain, too. If it's too worn out then you'll need to get a new one.

When the sprockets throw the chain it means either the chain links have stretched, or the teeth on the sprockets have worn out.
Examine the teeth on the sprockets. If they are worn, you'll be able to see it. If they don't appear worn, your chain might have stretched. If the rear gear cluster is worn out you have to replace the cluster and the chain. Now, or later.

Your back wheel might be too far up. Try loosening the back wheel (with the chain already attached) and pull back on the back wheel. When you've got it as far back as it can go (without coming completely off) tighten it back up.

There can be several reasons. One, the chain has weared, and you need to replace it. Another is the deraileur adjustments the have a hi and low stops, they might be off. Go to a bike shop to have it adjusted.
Good luck!

It probably means that one of the links is bent. It would probably be best to just put in a new chain. If that doesn't work try changing out the derailer (if you have a multiple speed bike)

Either the chain is too loose or the wheel sprockets are misaligned. You might consider taking the bike to a bike shop to have it tuned.
