Jilakin Rock is a granite rock formation located approximately 15 km (9.3 mi) east of Kulin and approximately 25 km (16 mi) south of Kondinin in the central Wheatbelt region of Western Australia. It overlooks Jilakin Lake and is a prominent feature in the area, rising out of the surrounding flat plains. The rock is an inselberg and is situated in the south western part of the Yilgarn Craton. The town of Kulin was gazetted as Jilakin in 1913, but the name was changed in 1914 when the railway to the town was completed.
