No.

Explanation:

The definition of an irrational number is that it is a number that can't be written as a fraction of two integers.

We can write #-3# as:

#-3/1=-6/2=-9/3=-12/4=-15/5#

All of which are fractions of two integers. This means that #-3# can be expressed as a fraction of two integers, and therefore it is not irrational.
