Allen is an English spelling of Alan.

Alan is Celtic in origin and possibly means peace, handsome, hound or rock.

The Kabalarian Philosophy suggests this about those named Allen. This name gives him a strong sense of responsibility in business and material affairs and the practicality and determination to make a success of anything he undertakes. His ability to organize and direct the efforts of others enables him to excel in a managerial position as he grasps the concept of a goal as well as understanding the steps to be taken to achieve it. His name will allow him to develop breadth and depth of mind. He is able to retain facts and to grasp new information. He never seems to be out of his depth. Others may classify him as a know-it-all and although he may be respected, this characteristic is unlikely to endear him to his associates. He has a very responsible nature, is capable and mature, and is willing to assume a position as a pillar of the community.
