Kathleen Lynn Brown (born September 25, 1945) is an American attorney and politician who served as the 29th treasurer of California from 1991 to 1995.

After defeating Compton city treasurer Wesley Sanders in the Democratic primary, Brown faced Republican incumbent Thomas W. Hayes in the general election.

[2] Hayes, who had been appointed to the office a year prior, ran an advertisement asking voters if they “Remember Jerry Brown?” to tie her to her brother's unpopularity.

[4] In the spring of 1994, Brown appeared favored in the contest, with a Field Poll taken in April 1994 showing her with a 51 to 39 percent lead over the incumbent.

[5] By fall, however, polls had tightened considerably, which was partially credited to California's economic condition improving by election day.

[4] Brown ultimately lost to Wilson, with the Los Angeles Times concluding that she "changed issues too often and ran out of money".
