Actually, yes.  Many astronomy books have such data - although often limited
to the few hundred nearest and/or brightest.  Check out star catalogs for
data on more stars.

The data is all relative to a very nearby point in the galaxy: here.
And there's a catch - the 3-D coordinates are usually based on a spherical
coordinate system: right ascension, declination, and radial distance.
However, it's a fairly simple matter to convert those to Cartiesian XYZ
coordinates, which I assume you're looking for.

Now, if there's a source of *machine-readable* star catalog data,  I'm sure
a number of people might be interested. (Like me, for example)
