AS Eesti Kiviõli (, English: Estonian Oil Shale Co. Ltd.) was an oil shale company located in Kiviõli, Estonia. It was a predecessor of Kiviõli Keemiatööstus, a shale oil extraction company. The town of Kiviõli is named after Eesti Kiviõli.
Eesti Kiviõli was established in 1922. At the same year it opened an open-pit oil shale mine near Sonda, which since 1930 continued operations as underground mine.[1] After unsuccessful tests with the moving grate kiln, the company built four tunnel kilns between 1927 and 1938, manufactured by AS Franz Krull.[1][2] It built new shale oil extraction plants in 1932 and in 1938.[2] In the 1930s it became the largest shale oil producer in Estonia.[3] In 1939, it produced 70,000 tonnes of shale oil.
