Lotus Organizer is a discontinued personal information manager (PIM). Initially developed by Threadz, a small British software house, reaching version 3.0, it was subsequently acquired by Lotus Development Corporation and marketed as a Windows-based replacement for Lotus Agenda. For several years it was the unquestioned market leader until it was gradually overtaken by Microsoft Outlook.

Organizer used the skeuomorphic ″leather-bound personal organizer″ graphical metaphor for its user interface.
