Concepts and technologies are disclosed herein for device hold determination using bone conduction. According to one aspect, a device side transducer of a user device can receive a bone conduction signal from a user side transducer. The bone conduction signal can propagate through one or more bones of a user, such as one or more finger bones. An application can be executed by a processor of the user device to analyze the bone conduction signal to determine how the device is being held. In some embodiments, data regarding how the user device is being held by the user can be exposed to an application that is executable by the processor of the user device, an application external to the user device, an operating system that is executable by the user device, and/or a website.
