More than 44 per cent of Germans believe Muslims should be banned from immigrating, compared to 36.5 per cent in 2014, the Competence Centre for Right-Wing Extremism and Democracy Research found.
The poll found more than one in two (55.8 per cent) said the number of Muslims made them feel like strangers in their own country, while 43 per cent gave the same answer four years ago, the Die Welt newspaper reported.
It also showed more than one in three Germans believe foreigners only come to the country to exploit the welfare state and 35.6 per cent feared Germany had already been "dangerously watered down" by foreigners.
