The invention provides a baby carriage capable of being folded in a linkage mode, which comprises a hand push rod assembly, a front wheel support, two rear wheel supports, a sliding piece and two linkage rods, one end of the front wheel support is arranged on the hand push rod assembly in a sleeving mode and slides up and down along the hand push rod assembly, and the other end of the front wheel support is connected with the sliding piece. The two rear wheel supports are hinged in a crossed pivot mode and then hinged to the upper side of the front wheel support in a pivot mode, the two rear wheel supports are sleeved with the two sides of the sliding piece respectively, the sliding piece can slide up and down along the two rear wheel supports, and the bottom of the hand push rod assembly is hinged to the sliding piece in a pivot mode. One end of the two ends of the two linkage rods is hinged to pivots on the two sides of the front wheel support respectively, and the other end of the two ends of the two linkage rods is hinged to pivots at the two ends of the sliding piece respectively. When the hand push rod assembly drives the sliding part to slide downwards, the two rear wheel supports rotate to be close to each other, the two linkage rods drive the front wheel support to be close to the two rear wheel supports, and the front wheel support is driven to slide upwards.
