The '''Otteri Nullah''' is an east–west waterway which runs through north [[Chennai]], starting at the village of [[Mullam]] proceeding through [[Purasawalkam]] and then passing through [[Buckingham and Carnatic Mills]] before meeting the [[Buckingham Canal]] at [[Basin Bridge]].

The waterway is around 12 km in length with a catchment area of 38.40 square kilometres. It is the major outlet for rainwater in North Chennai. Along with the other major waterways of Chennai, the water remains heavily polluted in spite of many government efforts to clean it up over the years, including the relocation of many thousands of people from its banks since the year 2000.

Heavy rains in late 2005 caused the stream to flood, leading to extensive inundation into the surrounding areas of polluted water and a subsequent outbreak of diarrhoea and vomiting. In the wake of the floods, the local administration began investigations into widening the stream to prevent recurrence of such problems in the future.

In 2010, it was announced that Hydrological digital instruments would be installed along the Otteri Nullah to monitor rainfall.<ref name="hyrdoinstrument">{{cite news|title=Hydrological digital instruments along Otteri Nullah canal soon |url=http://www.thehindu.com/news/cities/Chennai/article830829.ece |first=Lakshmi|last=K|date= 15 October 2010|newspaper=[[The Hindu]]|location=Chennai|access-date=2012-11-07}}</ref>
