The invention discloses a rainwater bio-retention filtering device which comprises a retention pond (1), a retention pond water inlet and a multilayer filtering medium (2). The multilayer filtering medium (2) comprises a covering layer (21), a biological filtering layer (22) and a gravel drain layer (23), wherein the covering layer (21) is positioned on the uppermost layer, the biological filtering layer (22) is positioned in a middle layer and can cultivate plants (8), and the gravel drain layer (23) is positioned on the lowest layer. A perforated collecting pipe (4) is horizontally buried in the gravel drain layer (23), infiltrating holes (41) are formed in the perforated collecting pipe (4), and the perforated collecting pipe (4) is connected with a collecting pipe (5) penetrating the side wall of a retention pond body (11). The rainwater bio-retention filtering device is simple in structure, low in manufacturing cost and convenient to use, runoff and flood peaks can be effectively reduced, and water quality of rainwater runoff can be effectively improved.
