A system and method for providing home appliance control data, wherein a Java phone allows a user to select desired control data to be transferred to a home appliance from among a plurality of control data, and a control data provision server downloads to the Java phone the control data selected by the user and a Java application for execution of the selected control data at the same time. The Java application and the control data are downloaded through a one-time operation based on the user's selection, thereby reducing the number of Internet accesses and an Internet access time for downloading of the control data to the home appliance. Therefore, the control data can be transferred to the home appliance within a shorter period of time, resulting in curtailment of a communication fee to be paid.
