I just did a google search, try it sometime, you'll like it.
Anyway, just to be nice, here's what I found.
There are an estimated 200 species of maple trees, all in the family Aceraceae.
Here are the North American species:
amur maple Acer ginnala
bigleaf maple Acer macrophyllum
black maple Acer nigrum
boxelder Acer negundo
canyon maple Acer grandidentatum
chalk maple Acer leucoderme
Freeman maple Acer x freemanii
hedge maple Acer campestre
Japanese maple Acer palmatum
mountain maple Acer spicatum
Norway maple Acer platanoides
paperbark maple Acer griseum
red maple Acer rubrum
Rocky Mountain maple Acer glabrum
silver maple Acer saccharinum
southern sugar maple Acer barbatum
striped maple Acer pensylvanicum
sugar maple Acer saccharum
sycamore maple Acer pseudoplatanus
vine maple Acer circinatum
Of these, I've only used sugar maple, also known as hard maple or rock maple. It is a great wood to work with, very dense and stable and is used widely in furniture and many other things. I have also seen reference made (but never used myself) soft maple.
Probably of more interest is the FIGURE you can get with maple. Birdseye maple, quilted maple, fiddleback maple, etc. are very common and you can get some amazing looking wood.
So, depending on what you are planning to use the maple for (i.e. a workbench top would likely be made with hard maple, but a veneer for a table might be birdseye or quilted), you will have many options.
