Fish tacos originated in which Mexican region named by Wikipedia?

According to Wikipedia, fish tacos originated in Baja California, Mexico.

The Baja California style usually features grilled or fried fish in a corn or flour tortilla, topped with lettuce or cabbage, pico de gallo, and a creamy sour-cream or citrus-mayonnaise sauce. The combination reflects the peninsula’s coastal setting and became one of the region’s best-known contributions to taco culture.

Fish tacos are often associated with beach towns and seafood stands, but the exact origin story is not completely simple. Baja California is the regional answer given in the cited taco article, while nearby coastal areas also have their own seafood traditions and recipes. Veracruz, Sonora, and Oaxaca are important Mexican food regions, but they are not the location named by Wikipedia for the origin of this taco style.

In the United States, fish tacos were popularized especially by Rubio’s, a fast-food chain founded in California. American versions often use battered fish and cabbage slaw, while Mexican preparations can feature grilled fish and a range of regional sauces.
