  We present the first medium-resolution ($R\sim 600$) mid-infrared
(8-13.3\micron) spectra of 11 Be stars. A large number of lines are observed
and identified in these spectra, including, as an example, 39 hydrogen
recombination lines in the spectrum of $\gamma$ Cas. In the majority of our
spectra, all of the observed lines are attributable to hydrogen recombination.
Two of the sources, $\beta$ Lyr and MWC 349 also show emission from other
species. Both of these objects show evidence of [Ne II] emission, and $\beta$
Lyr also shows evidence of He I emission. We tabulate the effective line
strength and line widths for the observed lines, and briefly discuss the
physical implications of the observed line series. We also use a simple model
of free-free emission to characterize the disks around these sources.
