Are there any matriarchal religions?

There are a number of them both ancient and modern. They focus on/worship The Goddess.

Shaktism/Shaktidharma, Basaque Paganism, the beliefs of Minos, Wicca, and the Goddess Movement, all have a fundamental female Godhead.

Drow elves, from Forgotten Realms novels , are matriarchal religions.

The patriarchal religions tend to be the ones that are monotheistic, or that emphasize the male patriarch (generally variations of the Sun god) over the others. Non-patriarchal religions tend to have a pantheon with several female and male deities, rather than a supreme or solitary matriarch goddess. There are many many goddesses.

I believe Judaism was matriarchal at one time. Wicca is the first to come to mind.
