Hayabusa 2 (jaapani keeles はやぶさ2 'rabapistrik 2') on Jaapani kosmoseagentuuri JAXA kosmoseaparaat, mille eesmärk on uurida asteroidi 162173 Ryugu ja tuua sellelt Maale pinnaseproove.

Missioon startis 3. detsembril 2014 Tanegashima Kosmosekeskusest ja jõudis Ryugu orbiidile 27. juunil 2018.[1] Hayabusa 2 võttis Ryugult pinnaseproovid 21. veebruaril ja 5. aprillil 2019. Aparaat uuris Ryugut novembrini 2019 ja asus seejärel tagasiteele Maa suunas.[2] Kapsel pinnaseproovidega eraldus aparaadist 220 000 km kaugusel Maast ning see maandus 5. detsembril 2020 Austraalias Woomeras. Hayabusa 2 suundus uurima asteroidi 1998 KY26, mille juurde saabub 2031. aastal.[3][4]

Hayabusa 2 on edasiarendatud Hayabusast, mis uuris aastatel 2005-2007 asteroidi 25143 Itokawa.[5] 21. septembril 2018 eraldusid Hayabusa 2 küljest kaks kulgurit, mis maandusid edukalt Ryugu pinnale.[6]
