Phyllis Lindstrom (born in 1931 in San Francisco) is Mary Richards' snobbish, self-absorbed and interfering friend and downstairs neighbor.

The Lindstroms manage the large Minneapolis rental property where they live with Mary and upstairs neighbor Rhoda Morgenstern (Valerie Harper).

In the series' first episode, Phyllis actively prevents Rhoda from claiming a newly vacated apartment so Mary can move in instead.

Colleagues attempt to prevent the pair from running into each other at the station; when they do, self-centered Phyllis plaintively asks Sue Ann if any jobs are available on her show.

Phyllis (and Rhoda) later returned to Mary Tyler Moore for "The Last Show", the program's March 19, 1977 series finale.
