The short answer
Twenty to thirty minutes on a high-speed catamaran, around 45 minutes on a conventional ferry. The two islands face each other across a narrow channel, and this is the easiest crossing in the Cyclades.
That deserves saying plainly, because most ferry advice is about risk - book early, leave slack, watch the wind. This leg is the exception. It is frequent, it is short, and it is the one crossing you can reasonably improvise.
Use it to treat Naxos and Paros as one base with two islands.

One trap on this leg, and it is the only one.
The published range runs from about 20 minutes to 3h35, which looks alarming until you understand why. The short end is a direct hop. The long end is a boat that leaves Naxos, calls at other islands, and reaches Paros much later.
So the number that matters is on your ticket, not on the route summary. A three-hour crossing between two islands you can see from each other is not a slow boat, it is a different journey.
Two islands, one trip

Because the crossing is trivial, these two work as a pair better than almost any other combination in Greece - and they are genuinely different islands rather than two versions of the same one.
Naxos is the largest of the Cyclades and the most self-sufficient. It has a mountain interior, real farming villages, marble quarries with unfinished kouroi still lying where they cracked, and a west coast of long shallow beaches. It is the better island for a longer stay and for children.
Paros is smaller, prettier in the postcard sense, and the centre of the ferry network. Naoussa is the harbour town people fall for, and you can reach almost anywhere in the Cyclades directly from Parikia.
The natural split is to base on one and day-trip to the other, or to give each half of a week. Which one to sleep on is argued properly in Naxos vs Paros.
Both arrivals are easy

This is the other reason the leg is painless. On Paros you dock at Parikia, the main town, and step off into a street. On Naxos you dock at Naxos town, right under the Portara at the harbour mouth, and do the same.
Neither island makes you take a bus from a distant port to reach civilisation, which is not true of Santorini and is only partly true of Mykonos.
Buses meet the boats on both sides for the beaches and the villages.
Where it fits
This pair sits in the middle of the Cyclades, so it slots into any route. North to Mykonos, south to Santorini, west back to Athens.
If you are building a first island-hopping trip and want one base that keeps your options open, Paros is the strongest candidate on the network - and having Naxos twenty minutes away is a large part of why. See the island hopping guide.

Frequently asked questions
How long is the ferry from Naxos to Paros?
About 20 to 30 minutes on a high-speed catamaran and around 45 minutes on a conventional ferry. Some published services show up to 3h35 because they call at other islands on the way, so read your own ticket.
Can you day trip between Naxos and Paros?
Easily, and this is one of the few Greek crossings where that is genuinely true rather than technically true.
Which should I stay on, Naxos or Paros?
Naxos for a longer stay, a mountain interior and shallow family beaches. Paros for a prettier harbour town and the best onward ferry connections in the Cyclades.
Do I need to book this ferry in advance?
Less than any other leg on this site. It is short and frequent. In peak August, booking ahead still costs you nothing and removes a small risk.
Where do the ferries arrive?
Parikia on Paros and Naxos town on Naxos. Both ports are in their towns, so no transfer is needed to reach anywhere.
