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.
