Agnes Garrett (12 July 1845 – 1935)[1] was an English suffragist and interior designer and the founder in 1888 of the Ladies Dwellings Company.

[1] She and her cousin Rhoda Garrett were employed by London architect John McKean Brydon in 1871, giving them an entry into training that no other practice was willing to allow, as architecture was not considered suitable for women.

For example, she designed the fireplace for the entrance hall, which is now open to the public as a historical gallery within the refurbished UNISON headquarters building.

[1] At Jacob Bright's suggestion it was decided to create a London-based organisation to lobby members of parliament concerning women's suffrage.

The first committee included Garrett, as well as Frances Power Cobbe, Priscilla Bright McLaren and Lilias Ashworth Hallett.
