The present invention discloses a heavy oil hydrodemetallization catalyst and preparation and application thereof, the catalyst contains a carrier and a metal component supported on the carrier, the hydrogenation metal component is selected from one or more of VIB group metals and VIII group metals, the hydrogenation metal component is selected from one or more of the group VIB group metals and the group VIII group metals, the hydrogenation metal component is selected from one or more of the group VIB group metals and the group VIII group metals, and the hydrogenation metal component is selected from one or more of the group VIB group metals and the group VIII group metals. The content of the hydrogenation metal component is 0.3-20 wt%; the carrier has a double-peak pore structure, the pore concentration ratio is high, the proportion of the pore volume of small pores to the total pore volume is low, and particularly, the proportion of the pore volume of pores with the pore size of 4 nm and 10 nm or below to t
