RE: Gran Tierra Energy Inc.

Form 10-K for the Fiscal Year ended December 31, 2018

Filed February 27, 2019

File No.: 001-34018

Ladies and Gentlemen:

Our client, Gran Tierra Energy Inc., a Delaware corporation (the “Company”), is in receipt of the letter dated July 30, 2019 (the “Comment Letter”) from the staff of the Division of Corporation Finance (the “Staff”) of the Securities and Exchange Commission with respect to the Company’s Form 10-K for the fiscal year ended December 31, 2018 (File No. 001-34018) filed with the Commission on February 27, 2019 and amended on April 16, 2019.

In a telephone call with the Staff on August 7, 2019, we, on behalf of our client, requested that the deadline for responding to the Comment Letter be extended. The additional time is needed due to the time dedicated by management of the Company to the preparation and filing of the Company’s Form 10-Q for the quarterly period ended June 30, 2019.

Per our telephone discussions, this letter will confirm that the Company will submit its response to the Comment Letter on or before August 27, 2019.
