Tyldesley Coal Company was a coal mining company formed in 1870 in Tyldesley,on the Manchester Coalfield in the historic county of Lancashire, England that had its origins in Yew Tree Colliery, the location for a mining disaster that killed 25 men and boys in 1858.

The Tyldesley Coal Company was a British coal mining company that operated in the North West of England during the 19th and 20th centuries. The company was founded in 1853 by William Tyldesley and was based in the town of Tyldesley, near Wigan.

The company was initially formed to exploit the coal reserves in the area, and by the early 20th century it had become one of the largest coal producers in the region. The company employed a large number of miners and other workers, and it was one of the main employers in the area.

The company was responsible for several large-scale mining operations, including the Tyldesley Colliery, which was opened in 1854 and operated until it closed in 1962. The company also operated several other collieries in the area, including the Hindley Colliery, which opened in 1875 and was the largest colliery in the region.

The company had a strong focus on safety and welfare, and it was one of the first companies to introduce safety measures such as helmets and safety lamps. The company also provided its workers with housing, schools and other amenities.

The company was eventually taken over by the National Coal Board in 1947, and it ceased operations in the late 1950s. The legacy of the Tyldesley Coal Company is still visible today, with several of the former collieries still standing in the area. The company also left a lasting impact on the local economy and culture, and it is remembered as one of the most important coal mining companies in the North West.
