The Polaroid 900 is an instant film camera from Polaroid's early roll-film Land Camera line. It used Polaroid's pack-style instant film and was aimed at amateur snapshot users when introduced.

Sales data for the Polaroid 900 is extremely thin: a single recorded UK auction hammer result of around £30, which gives an indicative value but no reliable range. Today, what a Polaroid 900 sells for at saleroom level depends heavily on cosmetic condition and whether the bellows and shutter are working, and most examples trade as decorative or display pieces rather than working cameras.
