The Liquid Propulsion Systems Centre (LPSC) is a research and development centre functioning under Indian Space Research Organisation (ISRO).{{Cite web |url=http://www.lpsc.gov.in/ |title=LPSC Webpage |access-date=17 December 2013 |archive-date=17 December 2013 |archive-url=https://web.archive.org/web/20131217121434/http://www.lpsc.gov.in/ |url-status=live }} It has two units located at Valiamala, in Thiruvananthapuram, Kerala, and Bengaluru, Karnataka. LPSC is augmented by ISRO Propulsion Complex at Mahendragiri of Tamil Nadu.

LPSC is engaged in development of liquid and cryogenic propulsion stages for launch vehicles and auxiliary propulsion systems for both launch vehicles and satellites. Activities related to liquid propulsion stages, cryogenic propulsion stages and control systems for launch vehicles and spacecraft is done at Thiruvananthapuram. Precision fabrication facilities, development of transducers and integration of satellite propulsion systems are carried out at Bangalore. The developmental and flight tests along with assembly and integration are done at ISRO Propulsion Complex, Mahendragiri in Tamil Nadu.

The development of liquid propellant stages for PSLV, control systems for SLV-3, ASLV, PSLV and GSLV, satellite propulsion systems including those for INSAT and IRS and production of pressure transducers are done by the LPSC for India. The LPSC has developed indigenous cryogenic upper stage for Geosynchronous Satellite Launch Vehicle (GSLV) which was successfully test fired by ISRO on 4 August 2007. LPSC is currently developing a restartable LOX-Methane engine and stages for the Next Generation Launch Vehicle, which uses a reusable booster stage.{{Cite web |title=Multiple restarts of Launch Vehicle Stages - ISRO successfully carried out ignition trial using Spark Torch Igniter |url=https://www.isro.gov.in/ISROsuccessfullycarriedoutSparkTorchIgniter.html |access-date=2025-03-08 |website=www.isro.gov.in}}

LPSC's current director is Dr.M Mohan.{{cite news|last=Correspondent|first=Special|title=New Directors at ISRO centres|url=http://www.thehindu.com/news/national/tamil-nadu/new-directors-at-isro-centres/article6167830.ece|access-date=2 July 2014|newspaper=The Hindu|date=2 July 2014|archive-date=21 October 2022|archive-url=https://web.archive.org/web/20221021081857/https://www.thehindu.com/news/national/tamil-nadu/new-directors-at-isro-centres/article6167830.ece|url-status=live}}
