No, it is not an object, but it is usually in the same place in a sentence that an object would be. An object usually comes after a transitive verb; the subject performs some action on the object:

- The player kicked the ball.
.. (subject) (verb) (object)

With a form of the verb be (is, am, are, was, etc.), there is no action. This is not a transitive verb. If there is a noun or a pronoun following such a verb, it cannot be an object, since there is no action to be applied to it. Instead, it is the same thing as the subject. Such a noun or pronoun is called a "predicate nominative". That name comes from the fact that it is in the predicate (after the verb), and it is the same as the subject, which is always in the nominative case.
- Her favorite dessert is ice cream.
......... (subject). (verb)(predicate nominative)

The reason the distinction between the predicate nominative and an object is important is that if the word happens to be a pronoun, the form may vary with the case:
-Object: Pat saw him across the room.
-Predicate nominative: (On telephone) May I speak to Joe? / (Replying) This is he.

Thank you, Pete.
