I have read numerous articles today, regarding all the aspects of Nikon! I know that you can obtain an adapter for NIKON lenses, to mount to an EOS body! However, can you obtain the opposite? That is a Nikon Adaptor that will convert an FD (Canon MF lense) to a MF for a Nikon AF body, like the D200. You can do it with so many Nikon lenses, such as the Ai, etc! Hell, I learned to Manual Focus 35 years ago! I constantly do it with the D200 and others, so why can't I use the older high quality FD glass lenses! Seems like Nikon figured it out! GO FIGURE!! This is from a converted canon film guy, to a NEW Nikon digital guy! Shoot both ways, Never go home alone! PLEASE, JUST KEEP YOUR ANSWERS SIMPLE! (IF POSSIBLE-HA!)

The simple answer is that while such an adapter is possible, it would either a) not permit the lens to focus to infinity, or b) would have to contain optics, typically in the form of a mild teleconverter.
I do not know of such a product.

benveniste is right, there is no simple way to convert Canon lens to Nikon mount without hitting a lot of issues. Ignoring the physical size of the lens and the mechanics of connecting it, the main issue is the FFD or Flange to Focal distance. The FFD for the Canon FD lens is 42mm while for the Nikon F mount it's 46.5mm. That means there is a full 4.5mm of lens extension even if you could mount the lens flush to the mount.
Canon themselves hit exactly the same issue when tehy changed from FD to EOS mounts in the EOS FFD is 44mm. Their solution was to produce an "optical adapter" to mate FD lens to an EOS body. In reality it was just a mild (1.26x) teleconvertor.
Converting the other way, Nikon F mount to Canon EOS mount is a lot easier since the throat of the EOS mount is more than wide enough to permit space for both the Nikon lens and the adapter. And with -2mm of extention focusing on infinity is easy.
an adapter that you can take on and off needs to go from a thicker camera body to a thinner body (with the adapter thickness making up the difference)
If you transfer to a thicker body then the lens will only focus for a couple of feet like a macro lens and everything else beyond will be out of focus. (An optical element (lens) can be fitted into an adapter to correct this but (1.very hard to find (2. very expensive (3. you lose some quality and perhaps 1 f stop of speed.)
I know I re said what some posters said above, sorry but that is how i needed to write it for it to all make sense to me.
Currently I use an F2sb with a full stable of pre-ai nikkors. For digital I am able to use my nikkors with a removable adapter to the thinner EOS body. This also gives me full light metering capability unlike the digital nikon bodys...
There is an adapter available see this link http://www.rugift.com/photocameras/canon-fd-nikon-adapter.htm I have no experience of using one although there was article in Amature Photographer last lear that reported good results using a similar adapter - contrast was reported to be lower than modern lenses but resolution was reported to be extremely good with very little fringing or flare which is surprising given to lack of modern coatings etc on FD lenses.
