TheDonghae Line (Korean: 동해선) is a railway line connectingBusanjin station toSamcheok station inSouth Korea. The literal meaning of its name, the "East Sea Line," reflects its position along the nation's East coast. It merged with theDonghae Nambu Line on December 30, 2016, and will merge with theDonghae Bukbu Line.

In 2018, the East Sea Line was partially extended to Yeongdeok Station, and on January 1, 2025, the line between Yeongdeok Station and Samcheok Station was opened.

Major stations along the line include (in order):

• Bujeon station, terminal station of the line and terminus of theBujeon Line
• Sinhaeundae station, a popular resort beach in eastern Busan
• Gijang station
• Taehwagang station (formerly Ulsan), major industrial city and terminus of the Jangsaengpo and Ulsanhang Lines
• Gyeongju station (Singyeongju), historic city
• Pohang station, seaport and industrial city
• BEXCO station, where the G-Star gaming event is held
• Samcheok station

Plans foresee directKTX high-speed train service from Seoul to Pohang and Ulsan after the completion of the upgrades. From 2015, direct KTX trains are to reach Pohang from Seoul in 1 hour 50 minutes, cutting 33 minutes from the travel time with transfer at Gyeongju.^[1] Under the government's 2010 strategic plan for 2020, the entire line may see KTX service.^[2]

In the Busan–Ulsan section, higher frequency commuter rail service betweenBujeon andIlgwang began on December 30, 2016. Service operates approximately every 15 minutes during the peak periods and 30 minutes during the off-peak. The line is integrated into theBusan Metro network and accepts theHanaro Card andDigital Busan Card, as well as theT-Money card from Seoul.

At the time of thawing relations between South and North Korea, when the cross-border section of theDonghae Bukbu Line was reopened in 2007, the South Korean government considered the construction of a railway for freight traffic all along the east coast to the North Korean border.^[3][4] As part of the corridor, a new single-track, non-electrified line for 150 km/h (93 mph) would connect Pohang and Samcheok, the end of a branch of theYeongdong Line.^[5] new line is to connect to the existing railhead at Samcheok. Work started on the Pohang-Yeongdeok section on March 20, 2008, with a foreseen budget of 2,949.5 billion won for the entire line until Samcheok.^[6] As of 2009, progress reached 5.9% of a planned budget reduced to 2,831.749 billion won, and completion of the 171.3 km (106.4 mi) long project was planned for 2016.^[7] Under the government's 2010 strategic plan for 2020, the Pohang–Samcheok extension is to be further upgraded for 230 km/h (140 mph).^[2]

On January 1, 2025, when theYeongdeok Station toSamcheok Station opened, 12 stations were newly established as intermediate stations, including Yeonghae, Goraebul, Hupo, Pyeonghae, Giseong, Maehwa, Uljin, Jukbyeon, Heungbu, Okwon, Imwon, and Geundeok.
