Metro Line 53 ({{Langx|nl|Metrolijn 53}}), also known as the Gaasperplas Line (Gaasperplaslijn), is a line of the Amsterdam Metro running between Amsterdam Centraal and Gaasperplas metro station in Amsterdam-Zuidoost.{{cite web |title=GVB |url=https://reisinfo.gvb.nl/en/travel-information/line/GVB/53}} It is the eastern branch of the Oostlijn.

The Weesperplein–Gaasperplas route was opened on 14 October 1977 and replaced the busy bus line 56. On 11 October 1980, the extension from Weesperplein to Centraal Station followed.{{cite web | url=https://www.urbanrail.net/eu/nl/ams/amsterdam.htm | title=UrbanRail.Net > Europe > Netherlands > Amsterdam Metro }} Until 2013, almost only type M1, M2 and M3 rolling stock were in service on this line, which were built for this line between 1973 and 1980. In the period 2013-2015, these were gradually replaced by the new M5. Since then, CAF rolling stock has also been in service, and from 2019 to 2024 with S1/S2 light rail rolling stock. The latter rolling stock was replaced by the new M7 from 2023.
