A process for producing silicon carbide fibers, comprising the steps of spinning an organosilicon high-molecular compound to obtain precursory fibers, rendering infusible the precursory fibers to obtain infusible fibers, and baking the infusible fibers thereby to obtain silicon carbide fibers, characterized in that the baking is performed in an atmosphere selected from the group consisting of a hydrogen gas atmosphere, a dilute hydrogen gas atmosphere and an inert gas atmosphere, with the proviso that the baking at any temperature in at least a part of a temperature range from 500 to 950 °C is carried out in a hydrogen gas or dilute hydrogen gas atmosphere.
