The IBM Personal System/55 Note (stylized as PS/55 note) is a series of notebooks manufactured by the IBM subsidiary IBM Japan as part of the IBM Personal System/55 series.

Machine type 5523 were designated as 'notebook' computers distinct from type 5535 which were larger 'laptop' multistation computers.

The international IBM PS/2 Note series was based on the PS/55 Note series and used the ISA bus (with the final exception of the C52).
