Actually it's tricky- it's in the 2nd amendment. You could argue that the second amendment, which reads "A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed"
Consider the context of the amendment: a fledgling country with an economy heavily dependent on slavery (think columbus triangle yo). The reason a "well regulated militia" was so important for "the security of a free state" was to help remedy the problem of run-away slaves.
So yes, while the word "slavery" does not appear in the constitution, it is important to keep historical context in mind when having these discussions :)
