Bayt Tima (Arabic: بيت طيما) was a Palestinian Arab village in the Gaza Subdistrict, located 21 kilometers (13 mi) northeast of Gaza and some 12 kilometers (7.5 mi) from the coastline. It was situated in flat terrain on the southern coastal plain of Palestine. Bayt Tima was depopulated during the 1948 Arab-Israeli War. Its population in 1945 was 1,060.

During the Mandate period the village was inspected by the Department of Antiquities, and a number of ancient remains were noted, in addition to two Arabic inscriptions built into the mosque. In the cemetery located just south of Bayt Tima lies a worn mosaic pavement, suggesting an Ancient Roman or Byzantine presence at the site.

A 14th-century Mamluk-era mosque existed on the site dedicated to a certain prophet or local saint named "Nabi Tima". In the courtyard of the mosque and near it are imitations of Corinthian capitals and columns of gray stone. The remainder of the building was built in local kurkar stone. There is no mention of Bayt Tima in early Arabic sources and the inscription on the mosque is the only Mamluk association to it.

Bayt Tima came under Ottoman rule in the early 16th century, and in the 1596 tax records it was under the administration of the nahiya of Gaza, part of the Liwa of Gaza, with a population of 126 Muslim households, an estimated 693 persons. The inhabitants paid a fixed tax rate of 33,3% on a number of crops, including wheat, barley, fruit, almonds, sesame, beehives, and goats; a total of 21,200 akçe.

Marom and Taxel have shown that during the seventeenth to eighteenth centuries, nomadic economic and security pressures led to settlement abandonment around Majdal ‘Asqalān, and the southern coastal plain in general. The population of abandoned villages moved to surviving settlements, while the lands of abandoned settlements continued to be cultivated by neighboring villages. Thus, Bayt Tima absorbed the lands of Sama, Bayt Sam'an and Irza, mentioned separately as inhabited villages in the Ottoman tax registers of the 16th century.

In 1838, Beit Tima was noted as a Muslim village in the Gaza area.

The Ottomans constructed additions to the mosque, and the Egyptians under Muhammad Ali of Egypt reconstructed it in the 1830s. In 1863 the French explorer Victor Guérin visited Bayt Tima, noting that it had a population of 400 and mentioning the Mamluk mosque.

An Ottoman village list of about 1870 indicated 49 houses and a population of 159, though the population count included men, only.
