We investigate the Dirac quasinormal modes (QNMs) of the Schwarzschild-anti-de Sitter and Reissner-Nordstrom-anti-de Sitter (SAdS/RNAdS) black holes using Horowitz-Hubeny approach. For large black holes, the fundamental QNMs are the linear functions of the Hawking temperature, and the slope of the lines decreases as the charge increases. For intermediate and small SAdS black holes, the real part of the fundamental QNMs approximates a temperature curve but the corresponding imaginary part is almost a linear function of the radius of the black hole. The quasinormal frequencies for high overtones become evenly spaced and the spacings are related to the mass and charge of the black hole. We also study the relation between QNMs and angular quantum number and find that the quasinormal frequencies increase as the angular quantum number increases.
