Is There an Uncharted Game on PSP? No — Only PS Vita Got a Portable Entry

No. No Uncharted title was ever released for the PlayStation Portable (PSP).

Why Not?

• The series debuted in 2007 (Drake's Fortune), when PSP was already 3 years old and technically outclassed by PS3.
• Naughty Dog developed exclusively for PlayStation home consoles.
• Sony Bend Studio made Uncharted: Golden Abyss for PS Vita (2011), not PSP.

Closest Portable Experiences

• Uncharted: Golden Abyss (PS Vita) – Full prequel campaign, touch/motion controls.
• Uncharted: Fight for Fortune (PS Vita) – Card-battle spin-off.
• Remote Play: Stream PS3/PS4 Uncharted games to PSP (limited, laggy) or PS Vita (better).

If you want Uncharted on a handheld, PS Vita is the only official option.
