Lüliang or Lyuliang (simplified Chinese: 吕梁; traditional Chinese: 呂梁; pinyin: Lǚliáng) is a prefecture-level city in the west of Shanxi province, People's Republic of China, bordering Shaanxi province across the Yellow River to the west, Jinzhong and the provincial capital of Taiyuan to the east, Linfen to the south, and Xinzhou to the north. It has a total area of 21,143 square kilometres (8,163 sq mi) and total population of 3,727,057. The metro area of Lüliang has a population of 320,142 at the 2010 census.
Frank Langfitt of National Public Radio described it as "a modest-sized city by Chinese standards".
In 2010 the city had a GDP growth rate at 21%; at the time prices for coal were high and the city had an active coal industry. There were plans to build a new business district in Lüliang, and the city's mayor had strongly pushed for the plan. In 2014 the GDP declined by 2%. By 2015 due to a slowing economy plans in that city stalled and many apartment blocks were left unoccupied. By 2015 the mayor lost his job due to corruption.
