Was LittleBigPlanet Ever Released on Nintendo DS?

No. There was never an official LittleBigPlanet game released for the Nintendo DS, DSi, or 3DS.

Brand Ubiquity: LBP was PlayStation's flagship UGC platform (PS3, PSP, Vita). Players assumed a DS port existed.
Similar DS Titles: Several DS games shared LBP's "Play, Create, Share" DNA and are often misremembered as ports:
- Scribblenauts (2009) — Emergent puzzle solving, object summoning, level editor (limited).
- Kirby: Canvas Curse (2005) — Touchscreen platforming, drawing paths.
- Drawn to Life (2007) — Draw your hero/weapons/platforms. UGC focus.
- Mario vs. Donkey Kong: Mini-Land Mayhem! (2010) — Level editor, share via Nintendo Wi-Fi.
Sackboy Cameos: Sackboy appeared in ModNation Racers (PSP/PS3), PlayStation All-Stars, but never on a Nintendo platform.

Title	Platform	Year	Notes
LittleBigPlanet	PSP	2009	Full 2.5D platformer, create mode, ad-hoc share. Different levels from PS3.
LittleBigPlanet PS Vita	PS Vita	2012	Touchscreen create, rear touch panel, near-perfect port of PS3 mechanics.
Sackboy's Prehistoric Moves	PS3 (Move demo)	2010	Tech demo, not full game.

PS Vita (Hacked/Hen) — Best experience. LBP Vita + DLC + community levels (via NoPayStation / PKGj).
PSP (CFW) — LBP PSP runs well on 6.61 PRO-C2/Infinity.
Remote Play (PS4/PS5 → Phone/Tablet/PC) — Play Sackboy: A Big Adventure or LBP 3 streamed.

No DS version exists. The DS got Scribblenauts and Drawn to Life instead—both excellent creative platformers in their own right.
