Abstract: In this paper two tracker solutions for the conformally coupled quintessence model is obtained. The first solution is determined by dividing the evolution of the Universe into matter- and dark-energy-dominated epochs and then the allowed bound on the equation of state parameter is obtained, such that a tracker behavior results. For the other solution, the quintessence potential is assumed to be a linear combination of two exponential functions, allowing us to find an exact solution that can be a tracker by adjusting some parameters.
