This utility model belongs to the field of tent technology, and particularly relates to an inflatable tent, including a frame and a tent fabric. The frame is composed of multiple inflatable columns, each forming a connected inflatable chamber. It stands upright after inflation and collapses after deflation. It also has a preset curvature for forming the top wall frame, meaning the side near the top wall is not horizontal, allowing the center of the top wall to arch and preventing water accumulation. Each inflatable column is equipped with ground pegs and a first guy line, improving installation stability. The tent fabric connects adjacent inflatable columns to form the top wall, bottom wall, and multiple side walls of the tent, each with an entrance and multiple windows. The connected inflatable chambers ensure that the air pressure of each inflatable column is the same, preventing tilting and collapse due to pressure differences or wind, resulting in good stability.
