The iriver H100 series (originally iHP-100 series) is a series of discontinued portable digital audio players (DAP) made by iriver company and originally released in October 2003. The models in the H100 series differ mainly in hard drive storage capacity. The players were succeeded by the iriver H300 series.

- Wired remote with 128×64 pixel black and white LCD, which can control any function of the DAP (same as iMP-550)
- Built-in 1300 mA·h Li-polymer battery, advertised 16 hours playback time
- USB 2.0, supports USB Mass Storage (drag and drop music transfers)
- Upgradeable firmware
- Motorola Coldfire CPU at 120 MHz 
- 16 MB RAM (H110, H115) or 32 MB RAM (H120, H140)
The H100 series is equipped with a 1.8 inch (45 mm) form factor hard drive manufactured by Toshiba. Storage density has increased since their introduction, making it possible for users to replace the factory drives with higher capacity aftermarket models. Opening the case of the player voids the warranty. However, after the case has been opened the upgrade consists of simply unplugging the old drive and inserting the new one.
As of December 2005, the H120 can be upgraded with a 30GB single-platter drive (giving a 50% storage increase) and the H140 can be upgraded with an 60GB double-platter drive (giving a 50% storage increase). Due to differing physical sizes, the two drive types cannot be used interchangeably (i.e. a double-platter drive will not fit in an H120 casing).
As of 2008 The H140 can be upgraded using a ZIF to ATA conversion cable to take a larger capacity 1.8 inch non ata hard disk drive. The 240GB MK2431GAH ZIF drive has been used in the H140 and the 160GB MK1634GAL ZIF drive has been used in the H120.
The battery used in the H100 series is physically similar to the battery used in iPods and other DAPs. It is possible to replace the factory battery with a higher capacity one (up to 2200 mA·h has been reported) for greatly increased playback time. In some instances the polarity of the battery leads must be reversed, and the installation process will void your warranty.
RTC (Real-time clock)
Users have succeeded in adding an RTC chip to the player's main circuit board, allowing the device to display the current date and time as well as adding alarm clock functionality, accurate filesystem timestamping and last.fm logging. Note that Rockbox is the only firmware known to be able to utilize an RTC-modified H1xx.
