Nonthaburi Pier or Nonthaburi Pier (Pibul 3) (Thai: ท่าน้ำนนทบุรี, ท่าน้ำนนทบุรี (พิบูล 3); often called short: ท่าน้ำนนท์), with designated pier number N30, is a pier on Chao Phraya River located in the Tambon Suan Yai, Amphoe Mueang Nonthaburi, Nonthaburi Province, Thailand, considered as another main pier of Nonthaburi, apart from Pak Kret Pier.
It is the final stop for all Chao Phraya Express Boats, except the green-flag boat. A cross-river ferry service is also available to the Bang Si Mueang side of Nonthaburi.
The pier is situated next to the Nonthaburi Clock Tower and the Old Nonthaburi City Hall, a teak antique building dating back to the reign of King Rama VI. Today, it serves as a provincial museum and is registered as an ancient monument by the Fine Arts Department.
The surrounding area features restaurants, coffee shops, bakeries, banks, clothing stores, and a market. It also functions as a terminal for several bus routes.
In addition, the Chao Phraya River flows past the pier, making it a venue for the annual King's Cup Regatta held around mid-year.
