We present subarcsecond resolution millimeter-wave images of a circumstellar disk in the Bok globule CB 26. The presence of an edge-on disk is confirmed by the dust continuum morphology and the velocity field of ¹³CO emission, which displays a Keplerian rotation pattern about an axis perpendicular to the long axis of the dust emission. We deduce a mass of ∼0.3 M_☉ for the obscured central star. The disk is optically thick at millimeter wavelengths inside 120 AU, has a symmetric 20° warp beyond 120 AU, an outer radius of ∼200 AU, and a mass of at least 0.1 M_☉. We suggest that the CB 26 system is in an intermediate stage between deeply embedded protostellar accretion disks and the more evolved, perhaps protoplanetary, disks around T Tauri stars.
