The 1970 LPGA Championship was the 16th LPGA Championship, held June 11–15 at Pleasant Valley Country Club in Sutton, Massachusetts, southeast of Worcester.
In an 18-hole Monday playoff, Shirley Englehorn won her only major title, defeating 1967 champion Kathy Whitworth by four strokes. Englehorn bogeyed the second hole and parred the rest for a 74 (+1). Three years earlier Pleasant Valley, Whitworth had bested Englehorn by a stroke in 1967, after the pair had co-led after 54 holes. It was Englehorn's fourth consecutive victory during the 1970 season. Defending champion Betsy Rawls tied for 26th, 21 strokes back.
This was the third LPGA Championship held at Pleasant Valley in four years, and the third of seven in an eight-year stretch.
