CalDigit is a hardware manufacturer based in Placentia, California, specializing in Thunderbolt and USB-C docking stations, hubs, and storage solutions aimed at creative professionals. The company began in the mid-2000s producing high-speed external storage — starting with FireWire RAID devices and progressing through eSATA and PCIe RAID systems — before pivoting toward docking stations after Intel introduced Thunderbolt in 2011. Their first Thunderbolt Station shipped in 2013, and the company has been a Thunderbolt developer since the protocol's earliest days.

The brand is best known in studio and post-production circles for docks like the TS3 Plus, TS4, and TS5 Thunderbolt Stations, the Element Hub Thunderbolt 4 / Thunderbolt 5 hubs, the USB-C SOHO Dock, and storage products such as the Tuff nano portable SSD and AV Pro 2 desktop drive. These tend to show up on the desks of producers, engineers, and content creators who need to expand the limited port selection on modern laptops while feeding multiple displays, audio interfaces, and external drives off a single cable.

CalDigit operates as a vertically integrated company, handling research, design, and manufacturing in-house, with regional offices in the UK, Netherlands, Taiwan, China, South Korea, and Japan supporting its global distribution.

CalDigit has 2 products cataloged on Equipboard, including Computers & Peripherals. Their gear is featured by 1 artist, with the strongest followings in Pop, Hip Hop, and K-pop. Notable users include Suga (Agust D).
