The invention provides a macroporous phenolic resin and a preparation method thereof, an application thereof in adsorption of 5-hydroxymethyl furfural. The macroporous phenolic resin has the BET specific surface area of 400-1300 m /g, the pore volume of 0.3-1.5 cm /g, and the average pore diameter of 1-20 nm. The macroporous phenolic resin has the advantages of high specific surface area, high adsorption capacity and high adsorption selectivity; the rich pore structure is regenerated and recycled easily; the macroporous phenolic resin has rich hydroxyl functional groups, and the adsorption capacity of 5-hydroxymethyl furfural is greatly improved through hydrogen bonding and hydrophobic interaction, wherein the maximum adsorption capacity can reach 111 mg/g wet resin, and the elutionyield of the 5-hydroxymethyl furfural is more than 99.5 percent; high efficiency separation of the 5-hydroxymethyl furfural can be achieved. The macroporous phenolic resin is applied to adsorption separation of the 5-hydroxymethyl
