Flour Mill, Ipswich, Heritage-listed industrial building in Brisbane Street, Ipswich, Australia.

Flour Mill, Ipswich is a complex of attached buildings at 231 Brisbane Street, designed by George Brockwell Gill and built in 1901–1902 by Worley and Whitehead. The main milling section has three floors plus a basement that sits above ground at the rear because of the steep slope. It is load-bearing polychrome brickwork with pilasters, arches and string courses, a corrugated iron roof with a raised louvred timber ventilator, and a single-storey former flour store to the east whose ornamental parapet bears the date 1901.

Built in 1901–1902 for the Ipswich Milling Company Ltd, the mill was designed by architect George Brockwell Gill and erected by contractors Worley and Whitehead. It was one of a series of mills linked to Francis Kates, a Berlin-born miller's son who migrated to Queensland in 1858 and sat in the Legislative Assembly from 1878; the Ipswich mill was said to be his eighth. The property stood in his son Francis Henry Kates's name.

Radio station 4IP broadcast from the top floor starting in 1935, transforming the space from industrial production to media use. This shift reflects how historic buildings adapted to new purposes beyond their original function.

The building now operates as a retail center across four levels featuring specialty shops, dining options, and a function venue. Visitors can explore the different spaces at their own pace to appreciate both the architecture and current businesses.

The mill's flour was sold under the brand name "Snowcloud", and a 1905 advertisement for Wigfull and Bland used the name "Heatherbell" instead; the sources do not record what arrangement produced the change. The building also housed radio station 4IP from September 1935, reached by an external staircase on the western side.
