Amazonas 1 or Hispasat 55W-1 was a communications satellite based on the Eurostar 3000 satellite bus and owned by satellites operator Hispasat, based in Madrid, Spain. It was launched on 5 August 2004, with a launch mass of 4,5 ton, on a Proton-M Briz-M launcher to be located in the 61º W geostationary position.{{cite web |title=Amazonas 1 → Hispasat 55W-1 |url=https://space.skyrocket.de/doc_sdat/amazonas-1.htm |website=Gunter's Space Page |accessdate=1 November 2020}}

Amazonas 1 payloads were 36 Ku band transponders that provided communications services in Europe and America, and 27 C band transponders that provided services in America. In 2013 it was relocated to the 36º W position and replaced by Amazonas 3.

In March 2016, Hispasat announced that Amazonas 1 would be renamed as Hispasat 55W-1. Finally, the satellite was moved to a graveyard orbit and deactivated on 23 June 2017.{{cite web|title=Amazonas|url=https://www.hispasat.com/lib/pdf/es/Coberturas-Amazonas-1.pdf|language=Spanish|accessdate=1 November 2020}}{{cite web|title=El Amazonas 1 acaba su vida útil y es llevado a la órbita cementerio|url=https://www.hispasat.com/contenidos/notas-de-prensa/0/277-622---reorbiting-amz1_es.pdf|language=Spanish|accessdate=1 November 2020}}
