city, San Diego county, southern California, U.S. Located 35 miles (55 km) north of San Diego, Carlsbad lies along a lagoon on the Pacific Ocean just south of Oceanside, in a winter vegetable- and flower-growing district. Luiseño Indians long inhabited the location before Spanish settlement in the 18th century. Founded as a cattle station located along the Spanish Camino Real (royal highway) and settled by Anglo ranchers in the late 1860s, it was first called Frazier's Station but was renamed (1883) when its mineral waters were found to be similar to those of Karlsbad in Bohemia (now Karlovy Vary, Czech Republic). After the arrival (1885) of the Santa Fe Railway, the city's fine beaches spurred its development as a popular health resort and vacation destination. Electronics, biomedical, and high-technology firms and light industry supplement the economy. The city is the site of Legoland California, a family-oriented park that opened in 1999. Other popular attractions include the Children's Discovery Museum of North County, the historic Leo Carrillo Ranch, and the colourful Flower Fields. Inc. 1952. Pop. (1990) 63,126; (2000) 78,247.

city, seat (1889) of Eddy county, southeastern New Mexico, U.S. It lies on the right bank of the Pecos River. Founded in 1887 and first known as Eddy (for its founder Charles B. Eddy), it was renamed in 1899 for the European spa of Carlsbad (now Karlovy Vary, Czech Republic), because of nearby mineral springs that reputedly had the same mineral content as that of their namesake. The centre (since 1888) of a large irrigated district, the city is a shipping point for locally produced cotton, alfalfa, wool, petroleum, and livestock. Potash, discovered in 1926, is also mined in the vicinity. A branch of New Mexico State University is located in the city. Carlsbad is the gateway to Carlsbad Caverns National Park (19 miles 【31 km】 southwest), and Living Desert State Park is nearby. Inc. 1918. Pop. (2000) 25,625; (2006 est.) 25,410.
