The 2 Line, also known as the East Link Extension, is a light rail line serving the Eastside region of the Seattle metropolitan area in the U.S. state of Washington. It is part of Sound Transit's Link light rail system and runs for 10 miles (16 km) in the cities of Bellevue and Redmond. The line has ten stations between South Bellevue and Downtown Redmond stations and its first section opened on April 27, 2024. The full line with service to Downtown Seattle, Mercer Island, Bellevue, and Redmond, is planned to open in early 2026 and span 18 miles (29 km). The 2 Line will continue through the Downtown Seattle Transit Tunnel and share stations with the 1 Line through to Lynnwood City Center station.

The East Link project was approved by voters in the 2008 Sound Transit 2 ballot measure, with construction costs projected at $3.7 billion. The line will use the Homer M. Hadley Memorial Bridge, one of the Interstate 90 floating bridges, which was constructed in 1989 with the intent to convert its reversible express lanes to light rail. Early transit plans from the 1960s proposed an Eastside rail system, but preliminary planning on the system did not begin until Sound Transit's formation in the early 1990s.

The proposed alignment of the East Link project was debated by the Bellevue city council in the early 2010s, with members split on two different routes south of Downtown Bellevue; city funding for the downtown segment's tunnel was also debated and ultimately included in the final agreement. The alignment was finalized in 2013, after more than two years of debate, and delayed the beginning of construction to 2016 and the completion of the project several years beyond 2021. The Seattle–Overlake section was scheduled to open in 2023, but was postponed due to construction issues on the floating bridge section that resulted in the replacement of its plinths. As a result, the first section of the 2 Line opened in 2024 with Bellevue–Overlake service; it was extended east into Downtown Redmond in May 2025. The full line will include the world's first railway constructed on a floating bridge and is expected to carry 50,000 daily riders by 2030.
