Hanasaari (ruots. Hanaholmen) on Helsingin Sörnäisten kaupungin­osaan kuuluva osa-alue Vilhonvuoren, Kalasataman ja Sompasaaren alueiden välissä lähellä Merihakaa. Nimi on peräisin alueella sijainneesta täyttömaan alle jääneestä saaresta. Hanasaari on suurimmaksi osaksi voima­laitos­aluetta. Ensimmäinen voimalaitos rakennettiin naapuriin Suvilahden puolelle.

Pääartikkeli: Hanasaaren voimalaitos

Hanasaaren A-voimalan rakentaminen alkoi vuonna 1957, ja se valmistui 1960. A-voimalaitos toimi vuoteen 2000 asti ja sen jälkeen varavoimalana. 2006 tehtiin päätös sen purkamisesta.[2]Hanasaaren B-voimalaitoksen suunnittelutyöt aloitettiin 1962, ja laitos aloitti toimintansa 1974. Alueelle on suunniteltu asuinrakentamista, joka edellyttää maaperän puhdistustoimenpiteitä, sillä punatiilisen B-voimalan läheltä löydettiin vuonna 2006 syanidipitoisuuksia. Alueen pohjavesien puhdistus on kallista ja vaikeaa, ja kokonaisuudessaan se saattaa viedä jopa vuosikymmeniä.[3]
