Roads leading to the parliament have been cordoned off and bomb experts have begun investigations, reports say.
"We have detained a few people for questioning," an unnamed police official told Reuters news agency.
Reports said the rockets had been defused by bomb experts, but there was no independent confirmation.
The parliament is not in session.
One report said that the rocket and the rocket launcher were found in a patch of green across the road from parliament main government buildings.
They were recovered a day after a small explosion in a park not far from President Pervez Musharraf's army residence in Rawalpindi.
