Maitland B. Bleecker (25 January 1903 – 19 October 2002) was an American inventor and author who was instrumental in modern helicopter design.

Bleecker graduated from University of Michigan in 1924 and secured a position with National Advisory Committee for Aeronautics at Langley Field, VA.

This helicopter flew successfully, but the project was abandoned because of The Great Depression.

In 1937 he founded Atlantic Casting and Engineering Corporation and retired in 1945.

Upon his retirement, he purchased 1,500 acres (610 hectares) of land near West Milford, N.J. where he constructed Lake Sonoma, started a trout hatchery, and operated the Tapawingo Fishing Preserve.
