  The project to upgrade the CEBAF accelerator at Jefferson Lab to 12 GeV is
presented. Most of the research program supporting that upgrade, will require a
highly polarized beam, as will be illustrated by a few selected examples. To
carry out that research program will require an extensively upgraded
instrumentation in two of the existing experimental halls and the addition of a
fourth hall. The plans for a high-luminosity electron-ion collider are briefly
discussed.
