Garth Neil McVicar (born 1950 or 1951) is a New Zealand political lobbyist who founded the Sensible Sentencing Trust (SST) law-and-order advocacy group in 2001.

[3] In 2014, McVicar was ranked 62nd equal on the Reader's Digest Most Trusted New Zealanders list, ahead of Police Commissioner Mike Bush (79th) but well behind Chief Justice Sian Elias (33rd).

[10] On 1 April 2018, Garth McVicar drew controversy when he posted remarks on Facebook lauding the New Zealand Police for killing a man armed with a machete who resisted arrest in the early hours of Easter Sunday.

McVicar's remarks drew criticism from various people including prisoner advocates and a police officer, who stated that "shooting a human being is never a time to congratulate anybody.

However, he also criticised Edwards for alleged double standards in singling out the Trust for criticism while not calling for the names of recidivist violent offenders to be placed in a public database.
