LaCosta Tucker (born December 12, 1951) is an American country music artist who recorded in the 1970s and 1980s as La Costa.

In between entering beauty pageants and talent shows, she performed with Tanya in a band called the Country Westerners.

She graduated from Cochise College in Douglas, Arizona, and began working as a medical records technician as she sang in clubs and became Miss Country Music, Phoenix.

LaCosta met and married airline pilot Darrell Sorensen, who fathered her children and also managed her career.

Many of LaCosta Tucker's recordings are out of print, but a 2000 release, Sisters: An Anthology, contains some of her hits packaged together with Tanya's material.
