The Palm Centro is a smartphone marketed by Palm, Inc. beginning its release on October 14, 2007, offering the functionality of the larger Treo 755p in a smaller size.^[2]

The Centro is one of the last devices to run the Palm OS operating system. The successor to Palm OS is webOS, which debuted on the Palm Pre in June 2009.^[3]

Currently, the Centro still works with some carriers, but not with others. 2G GSM devices, such as the AT&T Centro, can no longer connect to the AT&T network. Verizon's and Sprint's 3G CDMA networks have also shut down in 2022, so CDMA Centro devices will only work offline.^[4]
