The Fearless Movement (in Spanish: Movimiento Sin Miedo; MSM) is a defunct progressive political party in Bolivia.

MSM entered into a political alliance with the Movement for Socialism (MAS-IPSP) on September 3, 2005 in advance of the 2005 presidential election.

Four members of MSM were elected to serve in the lower house of Bolivia's Congress when the party was in alliance with the MAS-IPSP: Javier Zavaleta, Marcela Revollo, Fabián Yaksic, and Samuel Pamuri.

In January 2012, the Fearless Movement proposed that the five uninominal seats representing the city of La Paz (including Zavaleta, Revollo, Yaksic, and Pamuri, as well as Guillermo Torres of the MAS-IPSP) be subjected to a recall referendum, thereby confirming or rejecting their current party allegiances.

Also, Rossío Pimentel Flores, from the MSM, carried the municipality of Oruro, something unexpected, since the Movement for Socialism has enjoyed strong support from that city.
