The invention relates to the technical field of telescopic driving, and provides a telescopic actuator and a steering column assembly. The telescopic actuator comprises a coaxial transmission mechanism which comprises a basic shaft, a transmission shaft movably connected with the basic shaft in a sleeving mode and a transmission piece movably arranged on the transmission shaft in a sleeving mode; the driving mechanism is connected with the sleeving end, sleeving the basic shaft, of the transmission shaft; the transmission shaft is driven by the driving mechanism, the transmission shaft moves along the basic shaft, and the transmission shaft drives the transmission part to move along the transmission shaft in the same direction as the transmission shaft. According to the telescopic actuator and the steering column assembly, the long telescopic stroke and the compact structural design are achieved through the coaxial transmission mechanism, and efficient and stable telescopic driving is achieved in combination with the driving mechanism.
