No. All prime numbers except for the number 2 are odd. However, most odd numbers are composite numbers. All even numbers greater than 2 are composite numbers. So, prime numbers do not need to be odd, since one Prime number is even. Also, composite numbers do not need to be even.

Here are some composite odd numbers:

9 = 3 x 3

33 = 3 x 11

75 = 5 x 15
