The Toei Ōedo Line (都営大江戸線, Toei Ōedo-sen; "Greater Edo Line") is a rapid transit railway line of the municipal Toei Subway network in Tokyo, Japan.

The entire line was originally planned to open in 1985; however, the project was temporarily frozen following the 1973 oil crisis and remained on hold until the mid-1980s. It commenced full operations on December 12, 2000; using the Japanese calendar this reads "12/12/12" as the year 2000 equals Heisei 12. The line is completely underground, making it the second-longest railway tunnel in Japan after the Seikan Tunnel.

On maps and signboards, the line is shown in magenta. Stations carry the letter "E" followed by a two-digit number inside a more pinkish ruby circle.

In fiscal year 2023, the Ōedo Line had the highest daily ridership in the Toei network, serving an average of 836,179 passengers per day. Despite this, it was the only Toei subway line to operate at a loss, incurring a deficit of 3.2 billion yen.
