Osaka Municipal Subway Line 9 (大阪市営地下鉄9号線, Ōsaka Shiei Chikatetsu Kyū-gō-sen) is a planned, but as-yet unbuilt, rapid transit line that would run from Suminoekōen in Suminoe-ku to Kire-Uriwari in Hirano-ku within the city of Osaka. While no timetable has been announced for its construction, it has the provisional name "Shikitsu-Nagayoshi Line" (敷津長吉線).
