New Lester Colliery was a coal mine operating on the Manchester Coalfield from the second half of the 19th century to the first half of the 20th century in Tyldesley, then in the historic county of Lancashire, England. It was owned by James Roscoe and two shafts were sunk in about 1865 on the east side of Mort Lane on the road to Little Hulton where Roscoe had sunk the Peel Hall and New Watergate pits.
