A collapsible bottle is particularly useful as a beverage bottle such as a water bottle or soda bottle which can be collapsed after its contents are emptied in order to reduce its volume whereby the collapsed bottles take up less space in trash receptacles, recycling bins and so forth. Diagonal and typically spiraling grooves are formed in the bottle to facilitate its collapse. Visual indicators on the bottle are intended to suggest to the user the need to collapse the bottle. These visual indicators may include arrows. Fingertip indentations or other grip surfaces are typically provided for rotating the bottle to facilitate its collapse.
