Zeved habat (Hebrew: זֶבֶד הַבָּת‎) or Simchat bat (Hebrew: שמחת בת‎) is a Jewish naming ceremony for newborn girls.

In the Ashkenazi community, namegiving ceremonies for newborn girls were not widespread and often limited to the father announcing the baby's name in the synagogue on the Shabbat, Monday, Thursday or other occasion when the Torah would be read following the birth. Sometimes a kiddush will be held at the synagogue for family and friends. In the 20th century, interest in traditional ceremonies for welcoming baby girls has been revived, and new ceremonies have evolved. These ceremonies are often known under the newly coined terms Simchat Bat or a Brit Bat. There is no explicit source in the Mishnah or Talmud specifying when girls should be named.

In medieval times, girls were named during Shavua Habat (lit. "week of the daughter"). In early German Jewish communities, a baby naming ceremony was developed for both girls and boys called a Hollekreisch, which literally translated to mean the giving of the secular name. The ritual took place after Shabbat lunch. The babies were dressed up, and boys were draped in a tallit. The book of Vayikra (Leviticus) was placed in the crib. The crib would then be lifted up and the following recited in German: Hollekreisch ! How shall the baby be called? Ploni Ploni Ploni (i.e. his or her name three times). This was done for boys who had received their Hebrew names at their brit mila already. Nuts, sweets and fruits were then distributed to the guests. The custom applied to both boys and girls.
