The Yilan Line (Chinese: 宜蘭線; pinyin: Yilán Xiàn; Pe̍h-ōe-jī: Gî-lân Soàⁿ) is the northern section of the Eastern Line of the Taiwan Railways Administration in Taiwan.

This railroad was completed in 1924 as the Giran-sen during Imperial Japanese rule over Taiwan.

In 2000, it was electrified between Badu and Luodong, while the remaining part was completed in 2003.

On 4 December 2020, a landslide buried a section of the line between Houtong and Ruifang Station in Ruifang District, resulting in the rail service disruption along the line.

[1] Emergency work was then carried out to remove the 10,000 m3 debris and to restore the overhead line.
