A nitrogen-containing branched polymer, an anion exchange membrane, and a method for preparing an anion exchange resin are provided. A molecular structure of the nitrogen-containing branched polymer includes a nitrogen-containing heterocycle, a branched structure, and an aryl group. The number of branching site of the branched structure is not less than 3. The aryl group is connected to the branching site of the branched structure through the nitrogen-containing heterocycle. The aryl group and the branched structure satisfy a relationship: A:B=80-99:1-20. A polydispersity index of the nitrogen-containing branched polymer is not greater than 2.6. A weight-average molecular weight of the nitrogen-containing branched polymer is in a range of 40,000 g/mol-500,000 g/mol.
