Lumbini College (Sinhala ලුම්බිණි විද්‍යාලය) or Lumbini Vidyalaya is a Sinhalese mixed school located in Colombo, Sri Lanka. Founded in 1929, the school was named as a national school in 2009.

Lumbini College was established on 18 February 1929, as the Havelock Town Junior Mixed School, with 114 students. Although the school was a mixed school, only girls had attended. The staff consisted of the principal, D. R. Balasooriya, and three teachers. There was just a single building built from wooden planks.

The school was originally situated in Skelton Road, Colombo. In 2010 the primary school section was moved to a location in Wellawatte as a result of growth in enrolments, merging with Wallawatta Maha Vidyalaya, which was renamed Lumbini College. The school's secondary classes have remained at the original location.

On 2 June 2014 the President Mahinda Rajapaksa formally opened the school’s sports complex, which contains with a gym, tennis courts and sporting facilities.

The school's alumni are known as Old Lumbiniyanas.^{[citation needed]}
