About 450 hectares (1,100 acres) of forest have been destroyed in a fire which began at around 10pm on Tuesday.
A spokesman for the local government said about 200 people and 50 homes had been evacuated in an area on the northeast of the island which is known for its agro-tourism.
Sor far, 130 people have been mobilized to try to put out the flames.
The Balearic island is seeing the worst forest fires in 15 years.
Spain is highly prone to forest fires in summer because of soaring temperatures, strong winds and dry vegetation.
Last year wildfires destroyed about 150,000 hectares of land from January to July, after one of the driest winters on record.
This year the winter was wetter and there have been fewer summer fires so far.
