The party's state spokesperson Jitesh Kamat confirmed the development.
Kamat would be replacing Joshi as the new state unit chief.
Joshi was removed from his post for "anti-party activities", Kamat said.
"The order to remove him was issued by the party's Goa desk-in charge Sanjay Raut," said Kamat.
Joshi was appointed as the president of the Goa unit of the Shiv Sena before the 2017 Assembly elections.
