The Guangtong–Dali or Guangda railway (simplified Chinese: 广大铁路; traditional Chinese: 廣大鐵路; pinyin: guǎngdà tiělù), is a single-track electrified railroad in Yunnan Province of Southwest China.

The line branches off from the Guangtong station, near Kunming on the Chengdu–Kunming railway and runs west to Dali City.

Difficulties in construction included 110,000 cubic meters of water inundation of the tunnels.

The new electrified line opened for traffic in July 2018, upping speeds from 60 to 200 km/h and doubling the track.
