Methods and apparatus to identify loads lost from vehicles are disclosed. An example apparatus to identify a load lost from a vehicle includes at least one memory, machine readable instructions, and processor circuitry to at least one of instantiate or execute the machine readable instructions to determine a first load carried by the vehicle at a first time, determine a second load carried by the vehicle at a second time after the first time, identify a lost load occurrence in response to a load difference between the first load and the second load satisfying a lost load threshold, and generate an alert indicative of the lost load occurrence.
