Johns Hopkins University
21st century

The early decades of the 21st century saw expansion across the university's institutions in both physical and population sizes. Notably, a planned 88-acre expansion to the medical campus began in 2013. Completed construction on the Homewood campus has included a new biomedical engineering building in the Johns Hopkins University Department of Biomedical Engineering, a new library, a new biology wing, an extensive renovation of the flagship Gilman Hall, and the reconstruction of the main university entrance.

These years also brought about the rapid development of the university's professional schools of education and business. From 1999 until 2007, these disciplines had been joined within the School of Professional Studies in Business and Education (SPSBE), itself a reshuffling of several earlier ventures. The 2007 split, combined with new funding and leadership initiatives, has led to the simultaneous emergence of the Johns Hopkins School of Education and the Carey Business School.

On November 18, 2018, it was announced that Michael Bloomberg would make a donation to his alma mater of $1.8 billion, marking the largest private donation in modern history to an institution of higher education and bringing Bloomberg's total contribution to the school in excess of $3.3 billion. Bloomberg's $1.8 billion gift allows the school to practice need-blind admission and meet the full financial need of admitted students.

In January 2019, the university announced an agreement to purchase the Newseum, located at 555 Pennsylvania Ave. NW, in the heart of Washington, D.C., with plans to locate all of its Washington, D.C.-based graduate programs there. In an interview with The Atlantic, the president of Johns Hopkins stated that, "the purchase is an opportunity to position the university, literally, to better contribute its expertise to national- and international-policy discussions."

In late 2019, the university's Coronavirus Research Center began tracking worldwide cases of the COVID-19 pandemic by compiling data from hundreds of sources around the world. This led to the university becoming one of the most cited sources for data about the pandemic.
