Procottus jeittelesii, the red sculpin or red Baikal sculpin, is a species of deepwater sculpin that is endemic to Lake Baikal in Russia. It is a freshwater fish that dwells under stones or in holes in the mud at a depth range of 0 to 800 m (0 to 2,625 ft). It is often found at around 100 m (330 ft), and is most abundant during the autumn and winter. From the late winter to the spring it breeds at depths of 5 to 30 m (16 to 98 ft). It can reach a maximum length of 18 cm (7. 1 in), but typically is 10–12 cm (3. 9–4. 7 in). It has a red spotted or banded pattern on a light background. The red sculpin resembles two of its close relatives, the smaller P. gurwici and the larger P. major.
