Mount McGregor is a mountain in Saratoga County, New York in the towns of Wilton, Moreau, and Corinth.

It was renamed after Duncan McGregor purchased it for back taxes and built a hotel called the Mountain House in 1876.

Drexel constructed a narrow-gauge railroad from Saratoga Springs and built the Hotel Balmoral at the summit with accommodation for 300 guests.

In 1885 Drexel loaned his friend, seriously ill former president Ulysses S. Grant, the use of his personal cottage on the mountain.

[4] In 1945 New York State purchased the facility from Metropolitan for convalescing veterans of World War II.
