The Beijing–Harbin or Jingha Railway (simplified Chinese: 京哈铁路; traditional Chinese: 京哈鐵路; pinyin: Jīnghā Tiělù) is the railway that connects Beijing with Harbin in Heilongjiang Province. It spans 1,249 km (776 mi). It is a very prominent route in the provinces of northeastern China.

Construction of the section between Tangshan and Tianjin began in 1881 as the Kaiping Tramway. This section is the second-oldest railway in China and the oldest still in use. (The oldest railway in China was the Woosung Railway in Shanghai, built in 1876 but dismantled and removed to Taiwan the next year.) Later this section was extended west to Beijing and east to Shanhaiguan. It was further extended to the east and reached Mukden (modern Shenyang) in Fengtian province (modern Liaoning) by 1912.

The railroad operated under or was known by several names, including:

Under the late Qing and during the early Republic, it was administered by and provided much of the revenue for the Ministry of Posts and Communications. It is now administered by the Ministry of Railways for the People's Republic of China.
