Vescera, also known as Ad Piscinam, was an ancient titular see and Roman colony in Roman North Africa. It has been identified as a site near Biskra in Algeria. It remains as a titular see of the Roman Catholic Church in the Province of Numidia.
The city was founded soon after the arrival of the Romans around 200 AD under Septimius Severus' and became part of the province of Numidia. As a major settlement in the border region, it was significant even then. Its name was apparently bowdlerized by the Romans to Ad Piscīnam ("at the piscīna"), implying the presence of important waterworks.
The city fell to the Arab armies during the end of the 7th century. A significant portion of the inhabitants of the area still descend from the Arab bedouin tribe of Banu Hilal, others are mainly Chaoui Berbers.

In the 20th century the bishopric was nominally re-established as a titular see and three bishops are known.
