Gravity acts upon matter - simply put, an attractive force between masses.
A vacuum is an absence of matter.
If you put in a speck of matter to test if it is attracted by gravity, (which it will be), you no longer have a vacuum.
Gravity acts across a vacuum so the Moon is kept in orbit for example across the vacuum (ok pedants I know it's not a true vacuum, even in space there are add particles drifting about) in between. If you isolate an area of a vacuum then within that area there is no matter and hence as, Brachio points out, there would be no gravity.
As per earlier answer;
You have a vacuum, into which you put something (a mass or particle of matter) in order to demonstrate the force of gravity acting within it, then it is no longer a vacuum. So it could be said that there is no gravity in a vacuum.
It's a bit of a Shroedinger's Cat or tree falling in forest making a sound type of argument.
The more practical answer is yes. As (say) a ball-bearing in a container that is otherwise a vacuum will be subject to the force of gravity.
I wasn't sure of the pitch of the question, and initially, I was going to say 'yes, of course there is'
That's all I have to say about that.
