Ostrakine (Ancient Greek: Ὀστρακίνη, Latin: Ostracena, Coptic: ⲟⲥⲧⲣⲁⲕⲓⲛⲏ, ⲧⲣⲁⲕⲓⲛⲏ) was an ancient Egyptian city at a location that is known as Ras Straki (Arabic: راس ستركي) or Gazirat El-Felusiyat (Arabic: جزيرة الفلوسيات) today.

The name of the Zaraniq Protected Area (Arabic: الزرانيق) is also derived from Ostrakine.

The city's name is believed to be derived from the Greek word "οστρακινος," meaning "earthen" or "made of clay," which is based on the word "οστρακον," meaning "earthen vessel" or "potsherd." The name is sometimes translated as "city of sherds" and is thought to refer to a concentration of potsherds found on the spot. While some scholars have suggested that the name may also be translated as "city of shells," this interpretation is less likely due to the lack of usage of the term "οστρακινος" in this context.

Ostrakine was located on the road between Alexandria and Gaza at Lake Bardawil, a saltwater lagoon near the Mediterranean coast of the northern Sinai.

Established as a harbour in the first century BC, near Sirbonis, the longtime border between Egypt and Syria, archaeological evidence suggests that Ostrakine was a centre of glass-making in the classical period. A bishopric during the Byzantine period, there is evidence of three Byzantine churches, and that the town remained important as a stop along the trade route in the early Muslim period.

Ostrakine has traditionally been thought to be the site of the tomb of the prophet Habakkuk and the martyrdom of James the Less
