Pak Phraek (ปากแพรก) is a subdistrict of Sawi in Chumphon. Its six villages include Rai Lang, Pho Si, Khoyong, Khokhot, Choeng Khiri and Don Sathon. The local authority identifies temples at Ban Rai, Choeng Khiri and Don Sathon as community institutions.
Sawi Subdistrict Administrative Organisation serves both Pak Phraek and neighbouring Sawi tambons. That shared service authority does not merge their administrative identities. The area's waterways connect with the broader Khlong Sawi system described by neighbouring Tha Hin; use the village name to distinguish addresses within Pak Phraek from the separate Sawi tambon.
