A method and system for controlling an engine clutch of a hybrid vehicle that may effectively select an engagement way of the engine clutch according to a state of the hybrid vehicle and a running state includes: detecting driver's demand torque; calculating sync speed torque that the motor outputs at a predetermined target speed for the sync engagement; detecting a state of charge (SOC) of a battery of the hybrid vehicle; calculate charging torque of an integrated starter-generator (ISG) operated by power of the engine; performing the sync engagement when speed of the motor is greater than the predetermined target speed for the sync engagement; and performing the sync engagement or the launch slip engagement based on the driver's demand torque, the sync speed torque of the motor, the SOC, and the charging torque when speed of the motor is less than the predetermined target speed for the sync engagement.
