Ronald Conrad MacKenzie[1] (May 3, 1934 – October 29, 2020) was an American attorney and Republican politician who served in the Massachusetts Senate from 1967 to 1977.

Their bill would have granted the Boston Redevelopment Authority the power to purchase land outside Fenway Park and sell it to a private developer.

[10] In November of that year, MacKenzie filed legislation to select a 4,000 acre (1,600 ha) site for the construction of a planned community that could house 250,000 people.

The committee recommended that the Department of Health control the storage of de-icing materials and ban their use if water sources become endangered.

[13] On August 13, 1976, a grand jury indicted MacKenzie and fellow Senator Joseph DiCarlo on charges that they extorted $40,000 from a consulting company.

According to the indictment, MacKenzie and DiCarlo threatened McKee-Berger-Mansueto, Inc. (MBM), the consulting company supervising construction of the University of Massachusetts Boston campus at Columbia Point, with an unfavorable report from the legislative committee investigating their contract unless they were paid.

After his release in October 1978 he did paralegal work in the offices of attorney Richard M. Riley and State Senator Michael LoPresti Jr. On August 19, 1981, the Burlington Board of Selectmen voted 3 to 2 to make MacKenzie the town's Director of Veterans' Services.

[19] In December 1983 the Massachusetts Board of Bar Examiners ruled that MacKenzie was eligible to be a lawyer in spite of his conviction.
