Abstract: This paper presents an observational overview of the properties of Be star disks. The presence of circumstellar gas around Be stars can be inferred from observations of the double-peaked emission line profiles, infrared excesses, and linear polarization. High spatial resolution interferometric observations have confirmed that the gas exists in a flattened disk. The geometry and angular size of the disks at different wavelengths can be used to probe the density structure. The combination of spectroscopy and interferometry can be used to study the kinematics of the rotating disks and investigate asymmetries that arise from one-armed density waves in the circumstellar material.
