The Merak Commuter Line or simply Merak Line, formerly Merak Local Train ({{Langx|id|Kereta Api Lokal Merak}}),{{Cite book |url=https://djka.dephub.go.id/uploads/202305/KP-DJKA_67_TAHUN_2023_GAPEKA_JAWA_2023.pdf |title=GAPEKA 2023 Jawa Dephub |publisher=Directorate General of Railways |year=2023 |language=id |access-date=2023-05-19 |author=Ministry of Transportation}} is a local commuter rail service operated by KAI Commuter that runs from Merak Station to Rangkasbitung Station in Banten, Indonesia. The service, which was reactivated on 1 April 2017, has a total travel time up to 2 hours and is a primary means of transportation for Merak residents to travel to Rangkasbitung. It is colloquially called the Dark Green Line due to its dark green ({{Color box|#24824D}}) coloured route on the Commuterline travel map.

Initially, train service for the Angke–Merak route operated under the name Banten Ekspres (Patas Merak).{{Cite web |date=2008-09-22 |title=Banten Ekspress Gantikan Kereta Patas Merak |url=https://metro.tempo.co/read/136662/banten-ekspress-gantikan-kereta-patas-merak |access-date=2023-04-05 |website=Tempo |language=id}}{{Cite web |last=Okta |first=Maria |date=2018-04-06 |title=Kereta Lokal Merak-Rangkasbitung, Gantikan Layanan KA Jakarta-Merak |url=https://www.kabarpenumpang.com/kereta-lokal-merak-rangkasbitung-gantikan-layanan-ka-jakarta-merak/ |access-date=2023-04-05 |website=KabarPenumpang - Jalur Informasi Penumpang Tiga Moda |language=en-US}} Since the enactment of the 2017 train travel chart (Gapeka) and the Rangkasbitung Line was established, Banten Ekspres was removed so that the Merak–Rangkasbitung line is only served by Merak Line.{{Cite web |title=Per 1 April 2017, Jadwal Perjalanan KA Berubah |url=https://www.dream.co.id/stories/per-1-april-2017-perjalanan-ka-berubah-170322l.html |access-date=2023-04-05 |website=Dream.co.id |language=en}}

On 1 October 2020, the Merak Local train operation, which was previously managed by Kereta Api Indonesia, was moved to its subsidiary KAI Commuter after obtaining an operating license from the Ministry of Transportation on 3 June 2020.{{Cite web |title=KCI Dapatkan Izin Operasi KA Lokal Merak dan Prameks |url=https://www.beritasatu.com/yudo-dahono/nasional/654115/kci-dapatkan-izin-operasi-ka-lokal-merak-dan-prameks |access-date=2023-04-05 |website=BeritaSatu}}{{Cite web |last=Pradana |first=Rio Sandy |date=2020-09-30 |editor-last=Puspa |editor-first=Anitana Widya |title=Oktober, KCI Jalankan KA Prameks Solo-Yogyakarta |url=https://ekonomi.bisnis.com/read/20200930/98/1298839/oktober-kci-jalankan-ka-prameks-solo-yogyakarta |access-date=2023-04-05 |website=Bisnis.com |language=id}}

On 1 June 2023, the Ministry of Transportation, via the 2023 Train Travel Chart (Gapeka), renamed the route from Merak Local Train to the Merak Commuter Line.
