In general: no.

If you want to prevent access to accidentally opened ports (e.g. some
application listens on a port without you noticing) you may still want
to implement a firewall, though. However, this doesn't necessarily
prevent malicious applications from receiving inbound traffic, and has
the disadvantage of additional code that may contain exploitable bugs of
its own.
