To obtain a multi-row air-cooled condenser in which the quantity of the air being sucked from a windward air intake port from being reduced when a strong wind blows through the underside of the air intake port.

The mufti-row air-cooled condenser 10 comprises air-cooled condensers 1 arranged substantially horizontally at a high position in multiple rows and columns and has square plan view. The air 7 sucked through an air intake port 2 opening downward ascends on the outside of cooling tubes 5 arranged in an air-cooled condenser 2 and cools down the steam flowing through the cooling tubes 5 thus condensing the steam. Each suction port 2 of the air-cooled condensers 11 arranged along the outer circumferential fringe 6 is provided with an angle θ inclining inner downward therefrom.
