Adaray is a short-line commuter rail service operating between Adapazarı and Arifiye in Sakarya, Turkey. Commuter service on the line was introduced in 2013 in order to compensate for the discontinuation of the popular Haydarpaşa-Adapazarı Regional.{{cite web |url=http://www.rayhaber.com/2013/05/adaray-ilk-seferini-gerceklestirdi/ |title=Adaray ilk seferini gerçekleştirdi |last=Özen |first=Levent |date=28 May 2013 |access-date=30 September 2017 |language=Turkish |trans-title=Adaray's first service has begun |archive-date=29 January 2019 |archive-url=https://web.archive.org/web/20190129064243/https://rayhaber.com/2013/05/adaray-ilk-seferini-gerceklestirdi/ |url-status=live }} Along with the three existing stations on the {{convert|8.4|km|abbr=on}} line (Adapazarı, Mithatpaşa and Arifiye), five new small stations, consisting of a single island platform, were added.

When regional train service to Istanbul was restored on 5 January 2015, via the Ada Express, Adaray served as a connection between the train's final stop in Arifiye to the city center of Adapazarı. Finally in 2016 the service was cancelled. On 29 October 2024 service restarted.{{cite web|access-date=29 October 2024 |date=19 October 2024 |title="ADARAY 29 Ekim Cumhuriyet Bayramı'nda hizmete başlayacak" |url=https://www.sakarya.bel.tr/tr/Haber/adaray-29-ekim-cumhuriyet-bayraminda-hizmete-baslayacak/23207 |work=Sakarya Büyükşehir Belediyesi}}
