The M20, officially referred to as the M20 Sefaköy–TÜYAP Metro Line is a planned rapid transit line in Istanbul.

The line was originally conceived as an extension to the M2 line but was later made into its own lines due to conflict and lack of communication between the opposition-controlled Istanbul Metropolitan Municipality and the government-controlled Ministry of Transport and Infrastructure and was later given the line code M20 on the vision map.
