Xenophobia

Xenophobia (from Ancient Greek: ξένος (xénos), 'strange, foreign, or alien', and φόβος (phóbos), 'fear') is the fear or dislike of anything that is perceived as being foreign or strange. It is an expression that is based on the perception that a conflict exists between an in-group and an out-group and it may manifest itself in suspicion of one group's activities by members of the other group, a desire to eliminate the presence of the group that is the target of suspicion, and fear of losing a national, ethnic, or racial identity.
