Joy Lynn Hofmeister (née Janosky, born September 7, 1964) is an American educator and politician who served as the Oklahoma Superintendent of Public Instruction from 2015 to 2023.

Hofmeister is a former public school teacher and owner of a Kumon afterschool program business from Tulsa, Oklahoma.

[9] In her formal campaign announcement, Hofmeister denounced what she called the Barresi "reign of terror," critiquing the incumbent for a "cookie cutter" and "one size fits all" approach to education reform.

[1][10] During the campaign Barresi requested copies, under Oklahoma's open records laws, of all emails Hofmeister had exchanged with Jenks Public Schools since 2007.

[22] In 2014, Oklahoma County District Attorney David Prater announced his office was investigating complaints alleging that Hofmeister's campaign for superintendent and a "dark money" PAC.
