We have carried out a multi-observatories campaign to get our own photometric time series and collected all archived public photometric data time series for the stars in our catalogue. Each time series was analyzed with the Lomb-Scargle and CLEAN periodograms to search for the stellar rotation periods. The measured rotational properties have been complemented with detailed information on multiplicity, membership, and projected rotational velocity available in the literature and discussed star by star. We have measured the rotation periods of 112 out of 117 among bona fide members and candidate members of the beta Pictoris association and, whenever possible, also luminosity, radius, and inclination of the stellar rotation axis. This represents to date the largest catalogue of rotation periods of any young loose stellar association. We have provided an extensive catalogue of rotation periods together with other relevant basic properties useful to explore a number of open issues such as the causes of spread of rotation periods among coeval stars, the evolution of angular momentum, the lithium-rotation connection, among others. Description: We provide three tables where the results of our photometric monitoring campaign and of our photometric and periodogram analyses are summarized. Table 1 lists the members and candidate members of the beta Pictoris association along with coordinated, magnitudes, colors, distances, projected rotational velocities and separation between the components in the case of multiple systems. Table 2 lists the rotation periods together with the uncertainty, the peak-to-peak light curve amplitude obtained from sinusoidal fit, the photometric precision, indication on the single/binary nature of the target, the name in the GCVS, source of photometry used to measure the rotation period, the photometric band, and the starting and ending HJD of the photometric time series. Table 3 lists the photometric time series that were used to measure the rotation periods. We list the HJD, magnitude (in absolute value if retrieved from public archives, in differential values if collected in our monitoring campaign, the uncertainty, the photometric band, and the name of the target.
