\begin{abstract}
Young binary star systems have associated gaseous disks that affect 
their evolution.  Strong tidal forces of a binary give rise to gaps that
separate circumstellar (CS) disks from the circumbinary (CB) disk. We
discuss two important processes that involve binary/disk interactions.
The first is eccentricity evolution of a binary embedded in a disk.  The
second is accretion of gas across the gap that separates CS and CB
disks.  These results may also have implications for the recently
discovered planets.
