The two companies did not release financial terms of the deal.
In a blog post announcing the acquisition Monday, Bump CEO David Lieb said the company's apps, which also include a photo sharing service, Flock, will keep working for now.
In a blog post from late March, Bump said that its namesake app was downloaded 125 million times. The Bump app was launched more than four years ago.
"The Bump team has demonstrated a strong ability to quickly build and develop products that users love, and we think they'll be a great fit at Google," Google said in an emailed statement.
